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.

:-)
