Hanging...

[Johnny Billquist <bqt%softjar.se@localhost>]

Ok. So after letting the 8650 run for a few days, it really stopped working.
I have no real clue to why. The machine did not crash, and it continued 
to respond to things like PING. However, it was totally unresponsive in 
all other ways.
It was not running out of swap, nor memory at the time it hang.

Looking in the debugger, I saw the following:

Anyone have any ideas? I'm going to play around with the machine, but as 
you can see, I'm not in the debugger anymore, so I can't really find out 
anything more from that hung system.
