That could be almost anything ;-)
If my assumptions are right and it really gets stuck in the syscall for 
initializing the rxevent deamon then it could be a deadlock or 
something similar ...

The syscall is waiting for afs_initState < AFSOP_START_BKG. Before that 
line it just deals with priority and such ...
Now I don't know if it gets there.

That's the most suspicious line to me for those symptoms. The rest of 
it is starting the deamon itself (actually it can get stuck there, too, 
but I don't think that'll be the case).

Could you enter some debug outputs there?? or don't you want to alter 
the code??
