 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?
