Need help in setting up NIC

Hi all

I am having some problems in installing a 'SMC Elite 16T' NIC card in my PC
running RH5.1, kernel 2.2.2 and would appreciate if someone can help me get
it going.

The NIC card is recognized during boot up: 
Apr 30 05:10:16 genx kernel: smc-ultra.c:v2.00 6/6/96 Donald Becker
Apr 30 05:10:16 genx kernel: eth0: SMC Ultra at 0x340, 00 00 C0 A2 EA 97,
IRQ 10 memory 0xc8000-0xcbfff.

But, dmesg shows lots of these error messages:
eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x43, t=20500.

Linux-networking newsgroup makes it sound like an IRQ conflict but looking
through the IRQs, there doesn't seem to be any conflicts.

*** Base address in 'dmesg' being different from base address in 'ifconfig'
is normal; says Ethernet HOWTO ***

Does anyone know what could be the problem here ?
