So, after running 10.8.4 with (Specs listed in sig) and freezefixapp (Which wasn't working.. Or so i thought!) here's the situation:
When running something that prevents system from sleeping (ie Torrent software) the computer will lock up at random intervals. Sometimes throwing a visible KP, othertimes just locking up completely. This also happens when you disable sleep/hibernate completely.
When this isn't running, system will hibernate, sleep and resume as normal. So bizarre, if anyone could shed some light on a possible solution it would be much appreciated. 2 weeks of re-installing and experimenting thus far has not helped.
P.S. I was trying to paste a log of the last kernel panic, but was not sure where i'd find it? I did try googling to no avail.
*Edit* Also forgot to mention, for this build I am running DSDT-less (Although I do have the file on hand if it makes a difference [It froze anyway with it].. In E/E nullcpupowermanagement.kext is in there for what it's worth.
