Weird. Just read over that after writing the below, so perhaps my 
suggestions below aren't so useful. Some, at least (IRQ lines).

Check out /proc/interrupts - if the NIC is sharing an interrupt with 
anything else, fiddle until it doesn't. Sometimes moving it to a 
different PCI slot helps, but often slot 4 and slot 5 share a PCI 
interrupt line so there may be no point in trying both.

'lspci -vvv' will tell you what PCI interrupt line (A, B, C, or D) the 
card is on, too. Try to avoid sharing this too. PCI 'officially' shares 
interrupts nicely, and usually does, but some buggy hardware may not.

If you're not using your onboard IO-APIC but do have one, try enabling 
it in BIOS and making sure linux uses it (kernel compile time setting).

Get a better NIC?
