Because of that I switched the lock checking on for .35.4 . The machine tends to die of sucking the batts empty while sleeping over night (that batt is ok..). Or it dies when resuming from suspend or when using Xorg (submitted already a bunch of reports on various issues, this beast is picky). .35.4 is the first .35 running on this machine. Sorry, I just checked, I only activated it for .35.4 . Config for .34 had it still disabled. Amongst others, those are now active: CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_MUTEXES=y CONFIG_DEBUG_LOCK_ALLOC=y CONFIG_PROVE_LOCKING=y Would you mind giving advice on which else debug parameter to activate w/o performance loss (it's a productive work place)?
