I believe I have figured out why the e1000 crashed my machine after .5 - 1 hours: The NIC was over-heating. I measured one of the NICs after the machine crashed with an external (cheap) temp probe. It registered right at 50 degrees C, and this was about 15-30 seconds after it crashed.


Ben, please send lspci -x on the hot nic.

Here is the lspci information, both -x and -vv.  This is with two of
the e1000 single-port NICS side-by-side.  I have also strapped a P-IV
CPU fan on top of the two cards to blow some air over them....running
tests now to see if that actually helps anything.  If it does, I'll
be sure to send you a picture :)

Thanks,
Ben
