I'm using a router and everything is set to 1,500. Moreover, the message
he is getting would seem unrelated to the DSL modem. OTH, the mod is
correct and it is loaded.

Having eliminated the obvious, this is probably an IRQ problem. Awhile
back I had a similar colloquy with someone and the problem was fixed
with a custom-compiled kernel (with apic). That is what I do and would
do.

There is one other possibility that I can think of. Comment out
everything in modprobe.conf except eth0, reboot to level 3 and see if
the eth0 driver loads properly. Then load the modules one at a time to
see where the conflict might be (I don't think - but I'm unsure - that
the stock kernel supports module unloading).

ANYONE ELSE?
