dmesg
Using vanilla Linux 4.4.13, hardware Intel 82865G
On boot, when i915.ko was activated, screen switches to native KMS mode,
but several lines at top is blank, followed by 2 scanlines of random pixels.
Other parts of text looks and scrolls fine, but the blank/random part stays
blank.
dmesg says:
[drm] stuck on render ring
[drm] GPU HANG: ecode 2:0:0x037fffc1, reason: Ring hung, 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.
