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 21:56:27 lapd eth4: Tx descriptor 0 is 00002000. (queue head)
Jun 27 21:56:27 lapd eth4: Tx descriptor 1 is 00002000.
Jun 27 21:56:27 lapd eth4: Tx descriptor 2 is 00002000.
Jun 27 21:56:27 lapd eth4: Tx descriptor 3 is 00002000.
Jun 27 21:56:27 lapd eth4: Setting half-duplex based on auto-negotiated partner ability 0000.
Jun 27 21:56:27 lapd eth4: Promiscuous mode enabled.
Jun 27 21:56:39 lapd NETDEV WATCHDOG: eth3: transmit timed out
Jun 27 21:56:39 lapd eth3: 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: Tx descriptor 1 is 00002000.
Jun 27 21:56:39 lapd eth3: Tx descriptor 2 is 00002000.
Jun 27 21:56:39 lapd eth3: Tx descriptor 3 is 00002000.
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

# cat /proc/interrupts

Here is my problem ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

15: 10 13 IO-APIC-edge ide1
NMI: 0 0

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

Thanx,
Cosmin
