[realtek] Having trouble with 8139too device

Forgive me if this is the inappropriate forum to ask for this kind of 
help.

I'm trying to install linux on a hp zv6000 laptop.  I have tried several 
distros, Fedora Core 4 test3 is working best, but the networking is 
working only sporadically.  Network seems to work okay in FC1 and Ubuntu 
5.04.  I get "link up" but "transmit timed out" errors, so I suspect some 
driver conflict or misconfiguration.  I rarely can get a dchp lease, but 
not usually.

I have included below the results of lspci, ifconfig, dmesg, rtl8139-diag, 
etc.

I have no idea how to debug this kind of problem.  Any input that can help 
me track this down would be greatly appreciated.
