Gleb,

Thank you very much for your reply.

I spent the day yesterday trying to reproduce the crash that I posted 
last week and you kindly replied to. This is due to the fact that I 
stupidly managed to overwrite the kernel.debug that I used to generate 
the stack trace. Sadly I could not cause the system to crash again with 
the same sb* errors.

I did however remove both the Berkley Packet Filter and IPFilter from my 
custom kernel to try and isolate the problem. This has caused the crash 
to occur in a different and more reproducible form. I have both 
INVARIANTS and WITNESS enabled, as you can see from my kernel conf. 
which is included at the end of this e-mail.

Below are the latest stack traces (using bge and then fxp NICs), kernel 
conf. and dmesg. Any help would be appreciated. This time I have a copy 
of both the core files and corresponding kernel.debug so I can hopefully 
provide you with any info you need.

Here is a stack trace when I am using the bge NIC driver (which I've had 
reports on the freebsd-amd64 list as being unstable under load):
