Anyone ever have a problem where they leave the system running (no auto sleep) at all times but come back later to a system that is still running yet the monitor doesn't wake? I have yet to figure out what the issue is. Seems to happen every few days. Only way to correct it is to reboot. It seems like the system might have gone into a KP or similar because using volume up/down on keyboard makes no sound, trying to initiate spotlight doesn't get the hard drive cranking as usual but without the video output turning on I don't know how to confirm the problem.
Wondering about the stability of the Voodoo Power kext now (using it currently). Any thought at all? Any way to see what happened after rebooting?
I'm 99% sure your have a kernel panic, disable sleep screen and you'll see...
there is one known possible cause, is if you are using jmicronata and did not disable "HD sleep" in "energy saver" you'll get KP
if you did disable HD sleep
then the best bet is Voodoo Power being unstable as you thought... replace it with openhaltrestart, and see if you still have the problem
let me know, if it is unstable I'll remove it from the pack....
are you overclocking your machine?
