facing the same...
also number of desktop crashes increased. (from something around zero to one on two-three days)

so lets compare configs, i have got:
swappolube (dont think it is the cause, because it wasn't updated for months)
speedpatch (WAS installed, imo correctly uninstalled)
kp v49
overclock via maxcpu (widget)
latest cssu
open media player

i think it started with latest kp or the update of maxcpu, but it is merely more than a guess.
so any suggestions?
