For this bug it might actually be helpful to start collecting
information about the hardware it's observed on.

For us, the bug is hard to repro, despite us having tried on several
different machines (2 and 4 way SMP, Opteron and Xeon, tg3 and e1000
NICs).

If the bug is easier to trigger for you, please post a summary of the
hardware and anything unusual about your config (i.e. not default
bridged).

Thanks,
Ian
