Manually tweak, as it manually setting the media to 100baseTX
<full-duplex> and see if it still panics, or 10baseTX and see if it
still panics. I know you don't want to run at 10mbs, but if it works
without panics, that narrows down where your problems are coming from.

I also seem to remember other people having trouble with 3com cards and
the xl driver (I could be wrong, check the list archives for this list
and the -STABLE list) so I'll reiterate, test out a different make/model
of NIC and see if the problem disappears.
