01:57 mareko: I'm absolutely impressed by Steam's ability to run Battle.net flawlessly as a "non-Steam game"
07:24 kode54: I mean
07:24 kode54: there's a null ptr deref in an irq handler due to a race condition with set_drr
07:24 kode54: there's a patch in the ML
07:24 kode54: but it only covers DCN10 and DCN35
07:24 kode54: someone said there were other set_drr functions that should be patched
07:25 kode54: let me locate the patch
07:25 kode54: dang, they left
07:27 kode54: https://lists.freedesktop.org/archives/dri-devel/2024-September/468067.html
07:28 kode54: the crash presents as a system reset, since it panics during an IRQ
07:28 kode54: and since it happens during an IRQ, no log gets flushed to disk
07:31 kode54: looks like there are other places that reference funcs->set_drr that could be vulnerable to a race
07:32 kode54: needs to take a local copy of tg
10:47 Ristovski: kode54: oh so that's why they weren't getting anything logged
11:31 Venemo: Quibus: it could be either an issue with userspace drivers or the kernel driver. try to figure out what changed on your system when the issue started
14:11 Quibus: Venemo: I had the idea to try out older kernels indeed, but it's a bit tricky to reproduce on demand
14:12 Quibus: Ristovski: was the thing about nothing getting logged about my system?
14:12 Quibus: If yes, I'd like to know why nothing was logged as well :-)
15:58 _ds_: Quibus, sounds like one for netconsole (see https://wiki.ubuntu.com/Kernel/Netconsole). That should catch any log text emitted just before reboot.
16:22 Venemo: Quibus: it's either a change in the kernel or mesa or firmware or application. if neither, then it can be a HW defect
16:22 Quibus: Venemo: I do update my Debian installation daily and several times the kernel got updated
16:23 Quibus: But then I would have expected some kernel log about the incidents
16:23 Venemo: Quibus: if it's something that happens during video playback then a good suspect is a vaapi issue in mesa, you can try to disable hardware decoding in your apps and see if that helps
16:23 Quibus: TOday it happened when I was copying a file to a USB stick... no video playing at all
16:23 Venemo: Quibus: can you please repeat which kernel and mesa version you have and which GPU you use?
16:23 Quibus: (But before it was almost allways when playing video)
16:24 Quibus: Linux creator 6.10.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.10.6-1 (2024-08-19) x86_64 GNU/Linux
16:24 Quibus: model name : AMD Ryzen 9 7950X 16-Core Processor
16:24 Quibus: No separate GPU
16:33 Venemo: and which version of mesa?
16:36 Venemo: sounds like you have a Raphael GPU
16:37 Quibus: Mesa 24.1.3-2
18:39 Venemo: Quibus: okay, it doesn't appear super outdated, so if you believe it's a regression, I recommend to roll back to the versions where you are sure it worked correctly, and work from there
18:43 Venemo: alternatively, try the latest stable versions to see if the issue has been fixed or not
19:03 Quibus: Venemo: I always use the latest versions of whatever is in Debian testing. That's often quite recent
19:03 Quibus: Is there something lagging?
