Hello,

I've just triggered the bug again but _now_ without the nvidia proprietary 
module. Unfortunately, I hadn't enable the DEBUG options yet.

Nevertheless, It seems that the bug was triggered when the NAS was going to 
awake and that 2 user applications wanted to access it during his awakening.

Maybe it could give you some clues about where the problem could be (it seems 
to be a deadlock that occur when (maybe) the r8169 driver is waiting to serve 
one application and that an other one reclaim the same type of service, 
dunno...).

I will give you more information and a trace if I can obtain it.

Thanks

	Eric Lacombe
