 Hi,
 
 It seems that drm2 is doing in a lot of places allocation with WAITOK.
 I imagine that it is possible that this just hangs for some, especially
 on an older machine.
 
 Some of these can fail without problems, so I wonder if violently
 converting all WAITOK to NOWAIT will get you somewhere booting, if so
 we can narrow it down.
