No, not quite. After about 30 minutes of uptime and a moderate load of 
eth0 (100-200KB/s constant data flow) it happened again. :(

Aug 16 21:03:13 spot kernel: eth0: Tx timed out, lost interrupt? 
TSR=0x3, ISR=0x97, t=36.
Aug 16 21:03:15 spot kernel: eth0: Tx timed out, lost interrupt? 
TSR=0x3, ISR=0x3, t=141.

TSR=0x3, ISR=0x3, t=545.
[repeating endlessly]

I've booted a kernel without APIC and IOAPIC compiled and it works again.

I'm attaching a dmesg from a boot with IOAPIC enabled. I don't really 
know where to look for the problem here. The interrupt counter for the 
IRQ eth0 is using (a Realtek 8029 chipset) is growing significantly 
after a while. And after a while is seems to get stuck (Tx timed out). 
"ifconfig eth0 down" and "up" again did nothing. Sometimes it seems to 
fix such network problems.
