I have the same problem both with NFS or PVFS high usage. Disable SMP isn't possible! Actually I have 2 solution:
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 reach all bandwidth.
