>Description:
System ran with identical hw config 2.2-960612-SNAP without similar problems.
The system appears to run fine while process are running high (ie, complete
system rebuild).
when system is left idle, it will hang several after a while.
unable to determine length of "a while".
no messages are logged to console or to syslog.
CPU appears halted, num-luck does not respond, nor does Cntl-Alt-Del.
hang has happened every night since installing 2.2-960801-SNAP.

i will attempt to run a kernel with debugging, etc, to see if it
spits out an error message.
