 |
|
Just received this messag when switching from tty7 to tty12.
| Quote: | Feb 13 16:10:17 localhost kernel: [drm] GPU HANG: ecode -1:0x00000000, reason: Command parser error, iir 0x00008000, action: continue
Feb 13 16:10:17 localhost kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Feb 13 16:10:17 localhost kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Feb 13 16:10:17 localhost kernel: [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Feb 13 16:10:17 localhost kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
Feb 13 16:10:17 localhost kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error

Do I need to be concerned about (kernel is gentoo-sources:3.17.8-r1)? |

Not really, it's business as usual with the intel drivers...
It should keep running if you ignore the error, but it might be stuck in software rendering mode afterwards. Only a reboot will fix that. |

| If it happens with kernel 3.18 too, reporting a bug as suggested by dmesg would be a good idea. |
