6.2-STABLE (i386) Repeating crash (supervisor read, page not present)

Hi,

Recently I have noticed that one of our Dell PE1950's has been crashing 
a lot with the following reason "supervisor read, page not present".

The system runs 6.2 Release under i386.

I have attached 2 back traces, and I still have both cores if any more 
information is required.  Any light that can be shed on this problem 
would be greatly appreciated.

Tom

6.2-STABLE (i386) Repeating crash (supervisor read, page not present)

Are you running i386 on this platform to keep your network platform
homogeneous.  We run 6.2p2 on amd64 on the same hardware w/o issue.  

That's an interesting ARP issue; are you using bce(4)?  We prefer to
stack the machine with PCIe4x em(4) cards.

You might be hitting a bug in an obscure code path because of the
above errors.  I'm CC'ing someone who might be able to help.
