Comment # 7 on bug 67878 from Ben Gamari

From discussions with xexaxo in #nouveau, it seems that this might be a similar
regression to what happened in 3.8 (described in bug #59057). My plan is as
follows,

 1) Verify that 3.8.11 works
 1.1) If not, verify that 3.8.1 works and bisect to find the broken release
 1.2) If so, check whether 3.9 works
 2) Bisect backwards from the first broken release to 3.8.11 (or whichever
release was tested to work)
