I had the same problems as the one above.  I rememeber that
there is something not realy ok in the driver of the 3com905 series
cards.  This could be the reason that both machines are producing them
messages under heavy network load.  As they then might start to
busmaster. I will try to reproduct them errors my getting my
other machine to push a lot of data.  It's a cyrix 120Mhz so I hope
the cpu can handle it.

This problem was solved in my case by using Intel Pro 100 cards in all
my machines.
