linux 3.15.1

On kernels after ~3.14, some time after nouveau fails to initialize
(<60 seconds) ~all of userland becomes mostly unreponsive (cpu time
preemption?) [dmesg1]. The 'unresponsive' behavior starts
at around the same time 56.740245 happens.

I bisected, and found the first commit where this happens is
1f1ac3bf2a804911ad46076b10ce15364237a698. Removing this commit causes
the previous behavior: initialization fails as usual but nothing else
interesting happens.
