Freezes on FreeBSD Stable

[Rodrigo OSORIO]

Hi,

A few days ago I update my box to 8-STABLE (RELENG_8) and start 
experience freezes using the VLC application.
Of course no crashdump or trace to help diagnos the problem, so I start 
enabling some extra debug features in the kernel (kernel debug in the 
dev handbook) for ddb and so on.

At this point there is no result so if there is some extra stuffs I can 
use to allow verbosity and understand the problem, I'll try it.

regards

Rodrigo
