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 :)

Ben, I checked the datasheet for the part shown in the lspci dump, and it
shows an operating temperature of 0-55 degrees C.  You said you measured 50
degrees C, so you're within the safe range.  Did the fans help?

Here's the datasheet:

I get some strange e1000 failures too. It usually involves the watchdog kicking them back into order, but sometimes they'll stay offline for a while. Heat would explain it, though, because it only happens when I'm actually using the cards for a benchmark. I figured that it was either my cables, or a shoddy switch.

The new dual-port e1000 that I have doesn't seem to have this problem, even though I'm running 4 times more traffic than the singles that I had.
