NIC drops all packages

[Mark]

Hi.

I have a 3 NICs in a system, 1 onboard and 2 tulip-driver cards.
The tulip cards are identical. The builtin one is eth0, the two tulips are
eth1 and eth2.
They all go into the same switch and then on to the rest of the LAN. All 3
LEDs on the switch are green. Eth2 has green and orange lights.

Eth2 is dropping all packages, not one makes it through. I get a bunch of
these messages:
Jul 15 10:42:59 lvd2 kernel: NETDEV WATCHDOG: eth2: transmit timed out
Jul 15 10:42:59 lvd2 kernel: eth2: 21140 transmit timed out, status
f8922010, SIA 000003c0 ffff0001 fffbfb7f 8ff0c008, resetting...
Jul 15 10:42:59 lvd2 kernel: eth2: transmit timed out, switching to
100baseTx-FDX media.
Jul 15 10:43:07 lvd2 kernel: NETDEV WATCHDOG: eth2: transmit timed out
Jul 15 10:43:07 lvd2 kernel: eth2: 21140 transmit timed out, status

Jul 15 10:43:07 lvd2 kernel: eth2: transmit timed out, switching to
10baseT-FDX media.

Ifconfig for all 3 cards returns this:

Could the NIC be broken, or is this something else? Also, I just noticed
that eth0 and eth1 both use IRQ 5. Is that ok?
Trying to ping an address in eth2's network comes back with network
unreachable
If I switch the addresses of eth0 and eth2 I can ping the address that I
could not ping before.

Shutting all interfaces except for eth2 does not help either.

Thanks,
