I have recently (since the New Year) been experiencing regular GPU hangs
which typically render the system unusable.
During the hangs the kernel buffer is filled with messages of the form
[ 8269.599926] [drm:gen8_reset_engines [i915]] *ERROR* rcs0 reset request timed out: {request: 00000001, RESET_CTL: 00000001}
[ 8269.600022] i915 0000:00:02.0: Resetting chip for hang on rcs0
[ 8269.601827] [drm:gen8_reset_engines [i915]] *ERROR* rcs0 reset request timed out: {request: 00000001, RESET_CTL: 00000001}
[ 8269.602595] [drm:gen8_reset_engines [i915]] *ERROR* rcs0 reset request timed out: {request: 00000001, RESET_CTL: 00000001}
[ 8277.705805] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
etc.
Most recently the following message was displayed
[12796.753277] i915 0000:00:02.0: GPU HANG: ecode 9:1:0x00000000, hang on rcs0
[12796.753281] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[12796.753282] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[12796.753283] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[12796.753285] The GPU crash dump is required to analyze GPU hangs, so please always attach it.
[12796.753286] GPU crash dump saved to /sys/class/drm/card0/error
[12796.753304] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
Unfortunately, the /sys/class/drm/card0/error file contained only "No error
state collected".
bugs.freedesktop.org is no longer in operation so I decided to post here. Please
redirect me to the correct list if this is one is not appropriate.
My system info is:
CPU/GPU: Intel i5-8250U/Intel UHD Graphics 620
Kernel: 5.4.12-arch1-1
Video Driver: xf86-video-intel 1:2.99.917+899+gf66d3954-1 (mesa 19.3.2-2)
Let me know if any other information may be helpful.
