Not having much luck getting acceleration to work with my Thinkpad
x250 which has Broadwell HD 5500 integrated graphics. Immediately after
startx I get:
drm: GPU HANG: ecode 0:0x0fdffdff, reason: Ring hung, action: reset
drm: GPU crash dump saved to /sys/class/drm/card0/error
I tried to create the directory but it did not save anything. Anyone
know how to debug such problems? After a minute or so of rendering
corruption and hangs, Xorg.log finally says:
[ 96.773] (EE) intel(0): Failed to submit rendering commands,
... after which it seems to run OK.
I've already tried to update to the latest everything which has
proven pretty stable on my desktop setup with Radeon HD 5450 graphics.
 NetBSD-current, xorg-server-1.17.1 and MesaLib-10.5.1 from wip,
xf86-video-intel from git, libdrm locally updated to 2.4.60 since
it mentioned several intel fixes.
