Contents of /sys/class/drm/card0/error
Since upgrading my Intel NUC5i5MYHE with the Core i5-5300U CPU from Linux
kernel 4.0.5 to Linux kernel 4.1.0, I now get repeated GPU hangs about every 6
seconds starting immediately after boot. I have attached both the dmesg output
showing the hang messages and the contents of /sys/class/drm/card0/error, as
requested by the first hang message.
This is a headless system and does not have Xorg installed or running (only the
framebuffer console is active). The "monitor" attached is a dummy display
simulator dongle attached to a Mini DisplayPort to HDMI connector and not a
real monitor. Plugging in a real (DVI) monitor using another adapter yields
the same hangs, as does plugging in no monitor at all. While the real monitor
is attached, I can detect the GPU hangs as jerkiness in display updates, but
the console is still usable.</pre>
