I had an MX80 crash (insert sad face here) - worse problem was that it
did a crash dump and then did NOT reboot.  I have out-of-band serial
access to the console, so I could see that, after the dump completed, it
just printed:

watchdog: scheduling fairness gone for 240 seconds now.

every 20 seconds (with the seconds count increasing).  I had to open a
remote-hands ticket to get it power cycled.

Is there any way to for a reboot at that point?  Like, on old Sun
servers, sending a BREAK followed by certain other keys could get to the
firmware and hard-reboot the system, even with the OS was fubar.  Is
there anything like that on a Juniper?
