Bug#871639: NULL pointer dereference in reset_common_ring+0xc3/0x170 [i915]
Package: src:linux
Version: 4.9.30-2+deb9u3
Severity: normal
File: /boot/vmlinuz-4.9.0-3-amd64
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
I've been having issues with the i915 driver ever since I got this Skylake laptop.
The GPU is hanging every now and then. But the error handling has become worse
over time, from merely pausing a few seconds via X restarting, to now ooopsing
after updating to 4.9.30-2+deb9u3.
The issue started with a few warnings I've seen before, followed by the oops (which
is a new symptom AFAIK):
[drm] GPU HANG: ecode 9:0:0xffd7fffe, in Xorg [842], reason: Hang on render ring, action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
