[Karl Kastner <kastner.karl@xxxxxxxxx>]

Promptly had a kernel panic at the next reboot, which seems to be
related:

[drm:__gen7_gt_force_wake_mt_get [i915]] *ERROR* Timed out for forcewake to ack request.
...
Kernel panic - not syncing: Timed out waiting for forcewake to ack request.
---
Rebooting in 30 seconds.._

It is just strange that it happens only at every other boot.

Title:
  nouveau E[  PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]

Status in xserver-xorg-video-nouveau package in Ubuntu:
  New

Bug description:
  Since recently my trusty partition has problems booting into kernel
  3.19.0-25. At startup the message

  nouveau E[  PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]

  is repeated more than 3000 followed by

  nouveau E[   PFIFO][0000:01:00.0] runlist 4 update timeout
  nouveau E[   PFIFO][0000:01:00.0]  FB_FLUSH_TIMEOUT

  It then continues to regular log in, but every now and so on it
  freezes and a reboot is necessary.
