What type of system is it ? P3/P4/K7/K8 ? UP/SMP ? do you have a PCI-X
bus in it ? have you checked /proc/interrupts for strange behaviours ?

Not to my knowledge. I have several of them running on moderate volume
(50 Mbps) on production up to 50-60 kpps, and they have never ever caused
any trouble after 2.5 years. I even use others in stress-testing machines
which throw up to 500 kpps per port without any problem either. BTW, the
ones in the stress-testers are more recent, they are the ones with the
"toundra" PCI bridge.

Do you encounter the problem in only one system ? I begin to suspect a
hardware failure somewhere (CPU, RAM) which is triggered by higher loads.
