by greetings,
I am having some problems setting up an ethernet card based on realtek
(RTL8139) chipset. I'm trying this under both Mandrake 7.0/7.2, and both
gave me the same error.
I have 2 ethernet cards in the system: eth0 (tulip) is connected to the
internet, while eth1 (rtl8139) is connected to an linksys 5 port switch.
The only other computer connected to the switch is an Win2000 marchine,
using the same realtek network card.
All cables are new. In face, the switch is new as well.
The network works sometimes only. When it does work, I get the following
error message (using dmesg, as root):
eth1: RTL8139 Interrupt line blocked, status 5.
eth1: RTL8139 Interrupt line blocked, status 1.

here is the interrupts information:

it looks if eth0 and eth1 are sharing interrupt 9 through APIC. Is this
the source of problem? If so, how may I going to fix it?
any help is very much appreciated,
Elvis
