That seems to be a common problem.

It seems to me that it must be the driver. If you (and every one of us
who has reported this problem in the past) can get the card to start talking
again by only restarting the driver, then the driver must be at fault.

The only thing I can say is, "join the club". I have four machines and
four 8139-based cards and three different types of motherboards. Two machines
work ok, one occasionally shows this problem and one consistently shows this
problem. The two machines that show this have the same motherboard. Swapping
the ethernet cards around changes nothing.

It undoubtedly will. I've never had a problem with any of my machines
which have 3Com cards.

I suppose you could try the new driver which was just mentioned in the
The first public beta test release of "8139too" is now available for
download, testing, and non-production use from
Kernel 2.3.40 or later is required for use, though a 2.2.x-compatible
version is currently being developed.
"8139too" driver features improved performance, bug fixes, and
portability over the existing experimental "rtl8139" driver, from which
8139too is derived.
Testing feedback and patches are greatly appreciated. The README is
attached below for more details.
