Sorry about the question but, how can I fix the overrun problem? Changing the
driver? Bellow you'll some conclusions and, of course, other questions... :-)

I searched for the 3c59x module version distributed with RedHat Linux since
version 5.2 and I discover that: 5.2 (kernel 2.0.36) comes with 3c59x v0.99E
(5/12/98), 6.0 (kernel 2.2.5-22) and 6.1 (kernel 2.2.12-20) comes with 0.99H
(11/17/98).

My linux boxes with kernel 2.0.36 and 3c59x v.0.99H don't have the mentioned
problem, so no other system with the same module version like RedHat 6.0 and
6.1 should have the problem either, isn't it?

3Com modules didn't work, too. After your message I upgraded to 0.99L, the
latest version, until now... 

Now I have to wait some days to know if this upgrade solved the problem...
