With acpi=off noapic nolapic boot options the problem dissapears. The

When I upgrade from 7.10 to hardy my clock simple drift few seconds/min.

1) options forcedeth max_interrupt_work=200;
2) ro quiet splash noapic apic=off in grub's menu.lst.
The second still show the message too many iterations (6) in
nv_nic_irq but I
