I get something like this constantly with Steam:

[38494.104580] i915 0000:03:00.0: [drm] GPU HANG: ecode 12:1:84dfd7f7, in ChaosGate.exe [11646]
[38494.104588] i915 0000:03:00.0: [drm] ChaosGate.exe[11646] context reset due to GPU hang

Any ideas? This is now KDE6/X11 but the similar hang happens also with Wayland.

CPU is i9-13900k, GPU is ARC A770 and OS is Tumbleweed. Kernel is latest mainline but this has happened also few previous kernel versions.

Also this seems to happen with any possible game but all of them are Windows games running with Proton.

@jani you know how fix or workaround this? :-) Never happened with same machine only exception being NVIDIA RTX card instead of Intel. Has been ongoing issue for half years but I have had neither time nor interest to play anything that much so have ignored it so far.

The irony is that I bought Intel card exactly for better "out-of-the-box" state for system after installing OS ;-)

@timojyrinki let me remind that this happens neither with RTX nor with CPU heavy tasks such as compilation.

another different kind of workload where this does not happen is Bitwig Studio. So this is directly connected to this graphics card way or another.

I disabled upscaling (i.e. intel_pstate) but have not yet tried also disabling downscaling, which could be good test perhaps.

@timojyrinki i'm happy intel alumni but unhappy intel customer :-) does not match my quality expectations tbh.

@timojyrinki ya, switching to AMD is not an option ;-) And as said CPU has caused zero issues so far. Not like by ideology but do not want to spend moneyz.

Still a major turndown, i.e. owning a GPU that cannot do graphics.

@timojyrinki yeah, i'll start to grep kernel tree, and see where the messages emit.

@timojyrinki unrelated side-note, i don’t undestand why people put this cruft to new code in kernel:

 * Authors:
 *    Eric Anholt <eric@anholt.net>
 *    Keith Packard <keithp@keithp.com>
 *    Mika Kuoppala <mika.kuoppala@intel.com>

Nobody cares as Git has author field. Totally useless information.

@timojyrinki

GPU HANG is emitted by error_msg. Would be better of by being i915_error_msg or i915_error for easier grepping and inserting probes and this also supports it:

$ git grep error_msg|wc -l
244

@timojyrinki I use only LKML if I decide to post anything. I hate bug trackers, sorry :-) it is a kernel bug so LKML is way to go. Going to ignore web forms for sure.

@timojyrinki yeah i look up now to kernel tree, dig up all info that i possibly can and then post to LKML :-) and thanks for XE driver tip! i'll try it but i still look up first if i can find something nasty in i915 driver.

If XE driver is a fix, then this is also tumbleweed bug, ain't it @vbabka ?

@jani OK fair enough since both you and timo try to put me to fill out web form I will do it although it feels like torture :-)

I'll still look through kernel tree first see what I can find...

@jani fair enough :-) i'll do as good report as I possibly can and submit it...

@jani the breaking point doing something to this was after watching fallout pilot and wanting to start playing fallout 3 one again (with latest graphics mods) ;-) fallout made me do it

@jarkko That's very little information out of that log. Do you mind trying with drm-tip? mainline might be a bit behind.

@Andi I can try it once I have bandwidth. Thanks for tip!

@timojyrinki @vbabka there is some problem with sign on in SUSE sites. i've never been able to log in to that bugzilla. I've emailed to admins but they never have answered.

There was some other bug that I even fixed in OpenSUSE installation but I cannot remember what it was :-) I reported it here to mastodon only. I need to look that one up too if I ever get access to that bugzilla.

@jani @timojyrinki yeah sorry for mentioned that. i can admit that being irritated it just spotted my attention and ofc i went to complain about it here in social media :-) apologies!

@jani @timojyrinki that said prefixes do have measurable benefits for a developer! :-)

e.g. if have such prefix missing from some function that i maintain and i get a patch with that rationale, i most likely ack it despite being somewhat cosmetic change.

@Andi Luckily I've recently tested SGX cgroups patches with Tumbleweed, i.e. know how to compile equivalent distro kernel (as it is made for OpenSUSE) for any possible kernel tree :-) So can easily try this out once the bandwidth is available.

@timojyrinki @vbabka i've tried this a million times and with both of the major browser, no luck. opensuse bugzilla is inaccessible for me unfortunately.

@Andi Hey, running drm-tip really does fix any issues. I tried to play for about 20 minutes so it is not like very comprehensive test but in the past things have failed with 2-5 minutes so at least to the right direction.

@Andi OK so it still trips but at least the dump is longer now:

@Andi For what it is worth this was now in X11. I used it because thought it might be stabler with Steam. I can revert back to Wayland and see if that makes any difference.
