kernel trap 12 with interrupts disabled [bge0 on 7.2R]

[Chris Timmons]

Kostik,

Looking good after applying your patch and rebuilding the kernel.  I've 
been exercising the machine for a couple of hours under the same load 
which crashed it in short order yesterday.

I will report back if any problems appear.

Thank you for your help!

Regards,
-Chris
