I do get flash 9 (I know, not the best example) and tomboy to hang as 
reported by one of my Planet CCRMA users - flash 9 tested working on 
stock fedora 7 kernel - and both seem to hang in the same system call:

sched_getaffinity(3528, 32, <unfinished ...>

Full output of strace attached for both cases.

hm, that's weird. Is it completely unkillable at that time? Could you do 
a few things: enable CONFIG_PROVE_LOCKING (lockdep), and also try to get 
a full task state dump via:

  echo t > /proc/sysrq-trigger

thanks,

kill -9 does nothing. If there's another way to kill something let me
know :-) I'll try to get the dump asap. 

Hope you had a good time over the long weekend, you certainly deserve
some rest (and congrats over the scheduler inclusing in mainline!)
