@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 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

@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...

@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 ?

@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

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

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

@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 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.

@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 ;-)

I get something like this constantly with Steam:

[38438.072899] x86/split lock detection: #AC: ChaosGate.exe/11646 took a split_lock trap at address: 0x6fffe5f51242
[38441.268772] x86/split lock detection: #AC: ChaosGate.exe/11852 took a split_lock trap at address: 0x6ffff6801001
[38446.628277] x86/split lock detection: #AC: Loading.Preload/11762 took a split_lock trap at address: 0x6ffff6a3aee0
[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.

thanks! i'll check it out. however, would be nice if simply by cloning buildroot and selecting "external toolchain" it would just work :-)

@troglobit ya, it is not like a dev machine of any kind but still would be nice to have the toolchain for occasional use :-)
