Hi,
I can reproduce the bug on all my dell servers,differents generation (R710 (intel),R815 (amd), 2950 (intel).
They all use broadcom bnx2 network card (don't know if it can be related)
host kernel : rhel 63 with 2.6.32 kernel
guest kernel : 2.6.32 (debian squeeze, ubuntu).
No problem with guest kernel 3.2

While trying to reproduce the bug, we just detected that it depends on the hardware (mainboard) you run on.
