[openib-general] PCI-Express card loses connectivity on quad opteron

[patrick at fundum.net]

Hi,

I am testing the Mellanox Technologies MT25208 InfiniHost III Ex (Tavor
compatibility mode) (rev a0) PCI-Express card on RHEL 4 upd 4. The machine
is a quad opteron running on x86_64. I'm using the OFED1.1 package.

After moving some data (a few Megs with netperf) over the IB network the
IB card loses network connectivity. Pinging the card itself still works at
that point.


Any thoughts?
