I can't duplicate this error, but it's probably because my machine
doesn't have 4GB of memory.

I have one report in Febroary 2008 of another user encountering strange
oopses in 2.6.23.12 and 2.6.24 whenever he downed the interface.  I
suspect your experience is a repeat of that.

Just to be clear, you transfer about 200MB to the NIC (Rx direction),
then immediately reboot, right?  Can you duplicate the problem if you
simply ifconfig down instead of rebooting after the transfer?  

Thanks for your help.
