Hmm, unfortunately it seems like all the stack traces did not work.  There are 
lots of threads blocked on VM-related locks, and CPU 0 is running vm_daemon.
Probably would need a stack trace of that thread to see what it is doing (this
is part of why a real crash dump would be far better than a textdump as you 
can get more info after the crash instead of having to know in advance 
everything you want).  I saw earlier you had a thread to get textdumps to 
work.  Did you ever have regular crashdumps working?
