Subject: bnx2x crash dump on high  network load

I am seeing driver crashes with a bnx2x version 1.50.16. I have attached two crash dumps that I have captured.

I run Linux with the following kernel:

# uname -a
Linux sup-prj-441106 2.6.16.60-0.54.5-debug #1 SMP Fri Sep 4 01:28:03 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux

I am seeing these driver crashes when I run virtual machines (VMware Server) and those VMs do high bandwidth network I/O, so there are a lot of packets going through the NIC. 

Can you give me any hints for what the problem here could be?

Thanks,
Anna
