If there are any patches you want testing I have 3 very expensive 
paperweights sat around the office at the moment in the form of Dell 
PE2950's with twin adapters in them:

The easiest way to cause the watchdog time out on these systems is to 
write a file larger than 50Mb to an NFS file system that is mounted over 
UDP (TCP doesn't cause the time out strangely).  From the testing I have 
done the timeout is triggered when arround 49Mb has been copied to the 
NFS server. Perhaps this could suggest a bug in the udp packet checksum 
offload code?

I have 2 systems available to test on right now,  one running code from 
RELENG_6 just after beta2 was announced, and one cvsup'd from the uk 
mirror today.

The kernels are compiled with:

option INVARIANTS
option INVARIANT_SUPPORT

However this doesn't cause a kernel panic.

Let me know if you need any more information.
