GPU crash dump
Hello, I am filing a new bug, because all the similar bugs I found were
reproduced while running Xorg and/or chromium. I run linux in a console mode
only (KMS).
I am running linux kernel 4.4.6. It starts normally, without any warnings.
After that I am doing a kexec into another 4.4.6 kernel, configured
differently. This warning appears in dmesg. After the warning, system runs
normally.
here is the relevant information.
1. dmesg:
[ 4.741299] [drm] stuck on render ring
[ 4.742038] [drm] GPU HANG: ecode 7:0:0x87c3ffff, reason: Ring hung, action:
reset
[ 4.742040] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4.742041] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4.742042] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4.742042] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 4.742043] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 4.743293] drm/i915: Resetting chip after gpu hang
2. crash dump - attached
3. config files for the first and second (kexec-ed) kernel - attached</pre>
