Bug Description
Since recently my trusty partition has problems booting into kernel 3.19.0-25. At startup the message
nouveau E[ PFIFO][
is repeated more than 3000 followed by
nouveau E[ PFIFO][
nouveau E[ PFIFO][
It then continues to regular log in, but every now and so on it freezes and a reboot is necessary.

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.
