[realtek-bug] problems with 8139too driver

[Dusan Djordjevic]

I have one computer with 2 of this cards (not the same manufacturer, but same 
chip, realtek 8139). When I installed  Red Hat 7 both of them worked fine 
with supplied 2.2.16-22 kernel. But with new kernel (2.4.3, latest, with 
proper modutils) i have problems. It doesn't work. Ifconfig says that 
ethernet address is FFFFFF. On your support page you say that, in that case, 
PnP OS in bios should be turned off. But it is off from beginning.
cat /proc/pci is down. You will see that cards use irq10/0xe800 and 
irq5/0xec88. Same parameters they use with older kernel, and works fine.
