--- Comment #13 from Chris Paulson-Ellis <ch...@edesix.com> --- With that modification, the PTIMER warning goes away, but unfortunately I still have a hung machine with a black screen (serial console output below). I did the bisect and got it down to one of 4 nouveau commits - 3 that NULL deref, then 1 that hangs - see comment 8 above.
