but dmesg told me to file a new bug, so here it is.
Using Debian stable with kernel 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4
(2018-08-21) on Lenovo T580 laptop with the following device:
00:02.0 VGA compatible controller: Intel Corporation Device 5917 (rev 07)
(prog-if 00 [VGA controller])
Subsystem: Lenovo Device 225a
Flags: bus master, fast devsel, latency 0, IRQ 143
Memory at e7000000 (64-bit, non-prefetchable) [size=16M]
Memory at c0000000 (64-bit, prefetchable) [size=256M]
I/O ports at e000 [size=64]
[virtual] Expansion ROM at 000c0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: i915
Kernel modules: i915
I use zoom conference approximately once per day on average, and it crashes due
to this hang in about one out of 3 uses at seemingly random times while the
conference is on. I do not know how to reproduce this at will.
In my case the message was:
[275903.554471] [drm] GPU HANG: ecode 9:0:0x85dffffb, in zoom [29759], reason:
Hang on render ring, action: reset
[275903.554474] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[275903.554475] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[275903.554476] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[275903.554477] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[275903.554478] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[275903.554576] drm/i915: Resetting chip after gpu hang
[275903.554650] [drm] RC6 on
[275903.574354] [drm] GuC firmware load skipped
[275914.529457] drm/i915: Resetting chip after gpu hang
[275914.529542] [drm] RC6 on
[275914.547604] [drm] GuC firmware load skipped
Attaching the crash dump.
I wonder whether someone would be able to figure out a specific fix that could
be backported to Debian stable's kernel?</pre>
