1. What rndctl invocation causes this?  Can you share the output of
   `rndctl -l' (as root), if it doesn't freeze?

2. Can you interact with it in any way when this happens, like
   entering ddb -- either with C-A-ESC, or by arranging in advance to
   do `sysctl -w hw.cnmagic="+++++"' and then typing `+++++' at the
   console?  If so, can you share the output of `bt', `ps', `ps/w' and
   `show all tstiles'?

3. Can you get a crash dump?  (Can't remember if we support crash
   dumps on powerpc -- if not, we should.)

4. Can you reset the machine -- hardware reset, rather than reboot or
   power off and back on?  If so, can you get dmesg from the previous
   boot when this happens?
