IRQ sharing problem - 2.4.18 kernel

IRQ sharing problem - 2.4.18 kernel

[Lists (lst)]

Hi,
I have a TYAN Tiger 200T M/B with 2xIntel PIII CPUs at 1GHz and 1,3GB RAM. 
I'm using RadHat up to date and 2.4.18 vanilla kernel. On heavy load on 
ethernet interfaces (eth1,2,3,4) and scsi controller which are on the same 
IRQ (11) my server stops responding.

Thease are the erros given by kernel:
Jun 27 21:56:27 lapd eth3: Promiscuous mode enabled.
Jun 27 21:56:27 lapd NETDEV WATCHDOG: eth4: transmit timed out
Jun 27 21:56:27 lapd eth4: Tx queue start entry 4  dirty entry 0.

Jun 27 21:56:39 lapd eth3:  Tx descriptor 0 is 00002000. (queue head)

Jun 27 21:56:39 lapd eth3: Setting 100mbps full-duplex based on auto-negotiated partner ability 45e1

How  can I put the eths on different IRQs?
This is the IRQ router MAP table:
PCI->APIC IRQ transform: (B0,I6,P0) -> 5
PCI->APIC IRQ transform: (B0,I7,P3) -> 5
PCI->APIC IRQ transform: (B0,I7,P3) -> 5
PCI->APIC IRQ transform: (B0,I13,P0) -> 11
PCI->APIC IRQ transform: (B0,I14,P0) -> 11
PCI->APIC IRQ transform: (B0,I15,P0) -> 11
PCI->APIC IRQ transform: (B0,I16,P0) -> 11
PCI->APIC IRQ transform: (B0,I17,P0) -> 5
PCI->APIC IRQ transform: (B0,I18,P0) -> 11
PCI->APIC IRQ transform: (B0,I19,P0) -> 10

I tried to change the IRQs with pirq and ether at the boot time but it 
dosen't work.

Thanx,

Is this a Tulip NIC? If so, have you tried using the de4x5 driver
rather than the tulip one?

No. I have 2 Intel NICs and 3 RTL 8139 NICs ... the problems is not from 
the driver.

It dosen't works. If you have some experience in usage of pirq option 
please tell me how to use tha option.

Thanx a lot for the answers,
