In addition to my previous message, here's what I get from the debug log
facility:

Jan 10 22:56:51 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:51 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=33.
Jan 10 22:56:52 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:52 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=26.
Jan 10 22:56:53 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:53 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=30.
Jan 10 22:56:56 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:56 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=78.
Jan 10 22:56:56 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:56 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=32.
Jan 10 22:56:58 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:56:58 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=89.
Jan 10 22:57:00 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:57:00 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=77.
Jan 10 22:57:03 behemoth kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 10 22:57:03 behemoth kernel: eth0: Tx timed out, lost interrupt? TSR=0x3, ISR=0x3, t=171.

So yeah, I get timeouts allright...

Currently running NOAPIC, pity to see CPU1 receiving no interrupts at all... In the same debug log I now just saw this:

Jan 11 17:37:05 behemoth kernel: spurious 8259A interrupt: IRQ7

That's weird, since there's nothing there...:

cat /proc/interrupts
           CPU0 CPU1
  0: 232967 0 XT-PIC timer
  1: 6424 0 XT-PIC keyboard
  2: 0 0 XT-PIC cascade
  3: 138 0 XT-PIC serial
  4: 46201 0 XT-PIC serial
  9: 52 0 XT-PIC sym53c8xx
 10: 744329 0 XT-PIC eth0, eth1, usb-uhci
 11: 0 0 XT-PIC bttv
 12: 0 0 XT-PIC es1371, mga@PCI:1:0:0
 14: 19778 0 XT-PIC ide0
 15: 4520 0 XT-PIC ide1
NMI: 0 0
LOC: 232916 232914
ERR: 1

See? Nothing on 7... This is with NOAPIC (as you can see from the XT-PIC's in
the above dump). BP6 again?

Cheers//Frank
