freebsd stable - Feb 2010 - trap 12: page fault while in kernel mode on 8.0-RELEASE (possibly bge(4) related)

I'm having repeated kernel panic issues on 8.0-RELEASE/amd64. Can anyone
shed light on the below error? I unfortunately cannot provide a proper crash
dump. The pointer addresses are always the same. The only other thing I've
noticed that may be related is a watchdog timeout on bge0 error before the
panic. Thanks.

Any chance to get backtrace from the crash?
