The .19 patch actually installs without any major complaints... But to be
honest
I don't know if this is the source of the problems. The changes from
.19 ->.20
were pretty minor.  I could try the .19, is that currently what you use ?

Kernel Module.

The changes to the eepro100.c driver were made while back in the 82258 days
I don't know whether Benjie and those guys tested with 82558 or 9...

thanks,

Pramod
