Re: INFO: inconsistent lock state

Hi,

That msg appeared on one of our notebooks, one which is very
prone to panic. 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)?

Cheers,

Nils

# Older versions works OK? eg. 2.6.35 or 2.6.34?
