[lug] System dies occasionally - was: (no subject)

[Nate Duehr]

No one has mentioned this one yet...

Are there any power "saving" modes turned on in the BIOS?  Apmd running?

Perhaps a bug in one of those and the machine thinks it's "asleep"?

Just another thought...

Install works fine and the smp kernel (2.4.7-10smp ) appears to work, but occasionally (randomly, and not triggered by a particular application) the system goes dead (the monitor displays the 'no signal' warning) and will not wake up (the HD light just blinks, and the power light on the box is off).
