Freebsd 8.0 system freeze

[Peter Pieczora]

Hi,

You're absolutely right, adding dumpdev="AUTO" solved generating dump files.

I may be totally wrong, but it seems that wlan0 causes system panic:
I remember when using ndis device (linksys pcmcia wifi card) similar situation 
took place. 

 
Thanks for your help.
