sporadic freezes under load



Dear All,

I am seeing sporadic freezes. I have been observing this for some time
but cannot say anything specific about the circumstances.

It used to happen with 4.99.72 and seems to occur less frequently with
5.0. This is more a feeling than anything else, but it might be
related to iwn0, smp and higher loads?!? 

A typical scenario under which it would happen is watching video
while doing a cvs up on /usr/src.

Sorry for not being more specific. Any hints are welcome.

Best regards,

Marko
