forcedeth probems using linux 2.6.15-rc1

[Anders Peter Fugmann <afu@fugmann.net>]

Hi,

The forcedeth driver occasionally hangs, sometimes after several hours,
sometimes after just a few minutes of traffic. Hardware is a Nvidia NForce3 motherboard with onboard LAN
(Linux compiled for 64 bit, using gcc 4.0.3 prerelease). Removing and inserting resolves to problem for
a short period of time. The driver works without complaints on Linux 2.6.14.

The following is being printed to the kernel logs repeatably:
