(or in a but) 19:09:15 <waldi> yes 19:09:25 <carnil> yes I do not have a fresh mind at this hour anymore 19:09:50 <carnil> we have some other proposal in mails recently which we should pick 19:10:25 <carnil> do we skim through the bugs? 19:10:30 <waldi> what proposal do you mean? 19:10:57 <carnil> there is one from you abour further refining packages containing modules from some week ago, which I still have "unread" 19:11:08 <waldi> ah, okay 19:11:20 <waldi> yes, we can skim the bugs 19:11:38 <carnil> I tried to annotate each today, with more or less luck, let's start 19:11:47 <carnil> #topic #1126671: (S, M) linux-image-6.17.13+deb13-amd64: Disconnect root (path=/) during heavy load on NvME, partial corruption on NTFS.crash soon but not yet 19:12:01 <waldi> lets close this 19:12:12 <carnil> no news, bwh followed up, reporter did not followed up, I was suggesting to close the bu 19:12:15 <carnil> g 19:12:38 <carnil> right, then let's close it with a note to reopen if reporter can provide the answers 19:13:03 <carnil> #action carnil will close #1126671 as there was no further feedback from reporter (option to reopen) 19:13:14 <carnil> #topic #1111095: (i, M) firmware-amd-graphics: Radeon HD 8280 : gpu lock, black screen and crash. 19:13:33 <carnil> @ukleinek asked to test newer kernel, no feedback. If issue still present should be forwarded upstream. No upstream report found. 19:13:37 <carnil> -> wait so far 19:13:49 <carnil> #topic #1143500: (i, u) The Lenovo Legion Y9000X 2021 (Realtek ALC287 + Cirrus CS35L41) has no sound output through external speakers, but the headphones work normally 19:13:56 <carnil> this one got a followup from the reporter. 19:14:07 <carnil> tested newer kernels and claiming the issue is still there 19:14:33 <carnil> now this is not super new hardware 19:16:32 <waldi> and we even have a two year of bugzilla entry: https://bugzilla.kernel.org/show_bug.cgi?id=218744 19:17:00 <waldi> but this was a bug without proper logs. and most likely slop generated 19:17:37 <waldi> nothing useful to see right now 19:18:47 <carnil> okay let's just mark forwarded to the bugzilla one so we have some additional reference but let it as it is for now 19:19:19 <carnil> #topic #1143994: (i, M) general: Ethernet driver r8169 is used for RTL8125 chipset by default and disconnects intermittently 19:19:37 <carnil> No news. Do we still consider this bug actionable? Ideas? From earlier meetings @ukleinek will report upstream asking for directions. 19:19:52 <carnil> so I would leave the action with ukleinek here assuming he still wants to forward 19:20:12 <carnil> #topic #1144314: (i, u) refcount_t: addition on 0; use-after-free, regression from 260fbcb92bbe ("cgroup: Move dying_tasks cleanup from cgroup_task_release() to cgroup_task_free()") 19:20:43 <carnil> got this evening a patch to test from upstream, will do and then report back in the bug/to upstream, hopefully the reporter can test as well directly with their usecase 19:21:01 <carnil> #action carnil tests the patch from upstream for #1144314 and reports back 19:21:17 <carnil> #topic #1144857: (i, ) linux-image-amd64: LVDS panel turns off/on every few seconds on VALLEYVIEW graphics 19:21:29 <carnil> reporter did provide a bit more narrow range of versions. 19:21:53 <carnil> Any other ideas here than asking to bisect between 6.11 and 6.12.101? 19:22:16 <waldi> not really 19:23:18 <carnil> okay I will send the instructions from uau on bisecting the problem, this proved helpfull in other cases 19:23:26 <waldi> thx 19:23:33 <carnil> #action carnil sends bisect instructions for #1144857 to the reporter 19:23:45 <carnil> #topic #1145026: (i, M) linux-image-6.12.101+deb13-amd64: [REGRESSION] 6.12.101 breaks AMD SEV, SEV-ES, and SEV-SNP platform initialization 19:23:57 <carnil> reporter bisected problem, asked to forward -> wait 19:24:04 <waldi> maybe fixed upstream 19:24:08 <waldi> in 6.12.104 19:24:48 <carnil> #topic ah there was a followup wtoday which I missed 19:24:54 <carnil> ah there was a followup wtoday which I missed 19:25:08 <carnil> I will close the bug accordingly, it is resolved indeed 19:25:45 <carnil> #topic #1145111: (i, u+) linux: kernel NULL pointer dereference when running snapd testsuite 19:26:03 <carnil> aurel32 bisected the problem, reported upstream, there is a patch submitted but it did not yet land in mainline 19:26:30 <carnil> aurel32 prodded upstream again to point out that it needs to go to stable "soonish"/"sooner" 19:26:52 <aurel32> let's hope so, as it's a an easy way to DoS a system without being root 19:26:53 <carnil> I would prefer to wait until it really lands in mainline before we potentially pick it in advance 19:27:18 <carnil> aurel32: ack yes, you made that clear 19:28:33 <carnil> aurel32: please continue to keep an eye on it, notify when it hits mainline, then we can pick it in advance unless it floats then quickly to stable 19:28:43 <aurel32> ack 19:28:54 <carnil> #topic #1145141: (i, ) trixie-backports: CONFIG_NTFS3_FS disabled, breaks ntfs mount 19:29:25 <waldi> how did we get hardcoded ntfs3 this fast? 19:29:51 <carnil> For this one we need bwh I think. So we switched from ntfs3 to ntfs, but this affects the backports kernels. Either we revert the choice explicitly for bpo kernels or pick up the idea from bwh to make an alias. 19:30:14 <carnil> waldi: yes that is surpising, util-linux for instance got hit by this via as #1145441 19:31:01 <waldi> so util-linux is fixed? 19:31:15 <carnil> ntfs3 is quite badly maintained, there is a LPE issue open for some weeks now (altough upstream does not consider security issues mounting crafted images) 19:31:16 <waldi> but yes, lets just add an alias 19:32:07 <carnil> waldi: in unstable it is fixed yes, so no problem there. But in stable we have the problem that 6.12.y ships with ntfs3, and the bpo kernels ship with ntfs module, so adding an alias seems the most compatible way to not break in both cases 19:32:51 <carnil> waldi: ok I (or you?) will ask bwh on his thoughts? 19:33:15 <carnil> so that the next bpo upload ideally resolves this 19:33:34 <waldi> yeah 19:34:16 <carnil> ok I will ping bwh about it 19:34:55 <carnil> #action carnil asks bwh on opinions on adding an alias for ntfs module to ntfs3 for compatiblity in bpo kernels in stable on #1145141 19:35:03 <carnil> oh well that is not very understandable 19:35:15 <carnil> #topic #1145425: (i, ) linux-image-6.12.101+deb13-amd64: amdgpu Navi 23/W6600 flip_done timeout freezes display and requires hard reset 19:35:28 <carnil> that sounds familiar 19:35:44 <carnil> we had a couple of those, and recently upstream addresed the problem in 7.1.8 19:36:06 <carnil> but I'm not sure if that's the very same problem, but an option is to ask reporter to test the bpo kernel and see if the problem goes away 19:36:17 <carnil> but is running a bpo kernel an option for the user? 19:36:53 <waldi> i'll handle that 19:37:11 <carnil> waldi: thanks! 19:37:31 <carnil> #action waldi will handle/debug #1145425 19:37:45 <carnil> #topic #1145585: (i, ) linux-image-6.12.101+deb13-amd64: kernel panicked twice with timer cancellation 19:38:03 <carnil> reporter provided logs for analyzing 19:38:09 <carnil> I did not look into them 19:38:47 <waldi> weird system. testing, but stable kernel 19:39:31 <yunseong[m]> Can I looking it more? 19:40:05 <carnil> yunseong[m]: sure! 19:40:08 <waldi> you could look at the attached panic logs, see what they tell us. the initial two panics are already unrelated 19:40:53 <carnil> #action yunseong will look into information provided in #1145585 and do further research/debugging with the reporter 19:40:59 <carnil> yunseong[m]: ^^ fine? 19:41:32 <yunseong[m]> Yes, I will ask more about issue. :) 19:41:43 <yunseong[m]> * more about the issue. :) 19:41:43 <carnil> #topic #1145628: (i, u) src:linux: iwlwifi AC 9560 CNVi causes PCH bus deadlock on concurrent TLS traffic with Kernel 6.12 19:42:41 <carnil> slightly weird report. Apparently though newer firmware-iwlwifi fixes the problem, should we reassign there and consider it fixed with the newer version? reporter can use bpo version of firmware-iwlwifi? 19:42:46 <waldi> slop report 19:43:48 <carnil> it is surely generated with AI assistance 19:44:41 <carnil> just not sure if the assertion that just updating firmware fixes the problem for them 19:45:19 <carnil> but I'm bit tired of reading such report, so I basically skipped from the summary part to the "verified workaround" 19:45:39 <carnil> if you asserted to be it invalid let's close it though 19:49:00 <waldi> i have no idea if it is invalid. but it is unusable to find out 19:50:03 <carnil> let's close it and ask to properly fill it with reportbug kernel with full logs 19:50:13 <waldi> i'll do that 19:50:20 <carnil> grazie 19:50:41 <waldi> #action waldi will close #1145628 as unusable bug report and asked to come back with reportbug and all information 19:50:58 <carnil> #topic #1145677: (i, ) riscv64: Boot failure due to incorrect memory map 19:51:13 <carnil> waldi: you were already interacting here with reporter, we can leave it in your hands I guess 19:51:23 <waldi> no response from submitter on the question when it worked last 19:51:58 <waldi> the whole thing is weird as hell. the kernel thinks it runs with EFI, but the firmware does not. the kernel thinks it uses device tree, but the firmware is expected to do ACPI 19:52:48 <waldi> i would call this a firmware problem. completely unrelated to what the submitter thinks 19:53:12 <waldi> okay, yes, i'll ask again and without proper information just close it as well 19:53:43 <carnil> ack 19:54:51 <carnil> okay so we get late, do you still have some energy or do we skip the rest? There are in any case some annotations if someone want to look at the new ones 19:54:58 <carnil> (some are pending, waiting) 19:55:10 <waldi> lets cut it here 19:55:24 <carnil> good, so quickly through the rest 19:55:36 <carnil> #topic migration excuses 19:55:57 <carnil> 7.1.12-1 should migrate soon, would like to upload the final 7.1.13-1 one as well and then switch to 7.2.y to unstable? 19:55:58 <waldi> hmpf, i think i still did not fix the autopkgtest… 19:56:19 <waldi> okay. i uploaded linux-base with the config change 19:56:49 <carnil> waldi: i.e. we would be ready to switch 7.2 then to unsable, but should wait until linux-base migrates to testing 19:58:07 <waldi> just bump the dependency 19:59:21 <waldi> something else? 19:59:31 <carnil> no 19:59:35 <carnil> #topic AoB 19:59:42 <carnil> who will chair next week 19:59:47 <waldi> looks like it is my turn then 19:59:54 <carnil> thanks! 20:00:04 <carnil> #action waldi will chair next team meeting 20:00:08 <carnil> then we are done for today 20:00:12 <yunseong[m]> Thank you. Good night! 20:00:14 <carnil> thanks waldi and yunseong[m] for partecipating! 20:00:17 <carnil> #endmeeting
