Yep - if I take the cas card out the system runs great  - a lot faster
than the old Netra X1 I replaced :). It actually has a gem NIC too
which I have been using so I don't need to get this card working, but
I'm willing to test patches to see if they fix the panic (its a MMF
card though and I'm not setup to test if it actually works as far as
network connectivity, unfortunately).
