kernel error:too many iterations (6) in nv_nic_irq

[voltron81]

Hi to everybody.
I've a mailserver based on ISPConfig 3.0.1.6 (perfect debian server)
Monitoring the logs, I've seen this error in kern.log:

Somebody have an idea of this error?
Is that something seriuos?
Thanks

Hi,

This error mostly shows up in dmesg when the system is running on gigabit port.
So lot of times the bandwidth is not utilized properly.
The "to many iterations" part is harmless and can be ignored.

You can try out 2 solutions :

1) options forcedeth max_interrupt_work=200;
2) ro quiet splash noapic apic=off in grub's menu.lst.
