 Can you start crash(8) and get output from `ps', `ps/w', and `show all
 tstiles'?
 
 Can you start crash(8) and stack traces from the processes not in RUN
 state, like the tstile one with `bt 0t18154'?
 
 If you can't start crash(8), can you enter ddb instead by sending
 break over serial, or by (perhaps on the next boot) setting sysctl -w
 hw.cnmagic=+++++ and then typing `+++++' on the console?
 
 Can you ktrace the processes in RUN state to see what syscalls they're
 running?
 
 Can you run dtrace to sample what's happening?
 
 dtrace -n 'profile:::profile-97 { @[stack()] = count() }'
