That sounds like a hardware/network problem. A quick search of the net
finds a really good explanation of exactly what the driver is telling
you:

NOOOOOO! That driver is very bad. When I used to work in the IT
department at TurboLinux I used to change all of our machines from the
3com driver to the Donald Becker driver. The 3com driver:
o hung the machine for 5-10 seconds when configuring interfaces
o paniced machines when used too many times to reconfigure interfaces
o did not support altering the MTU (in source even) to over 1500 for
802.1Q routers
