I have attached niu related output from kern.log.
(cat /var/log/kern.log | grep niu | awk -F'kernel:' '{print $2}')

Yes, your latest tree.  Both with and without your latest change to the
niu driver (niu: Use pci_ioremap_bar().).

Also tried a debian 2.6.26-1-686, that kernel actually crashed (in
net_rx_action, __do_softirq, do_softirq, irq_exit, do_IRQ, mwait_idle).

A strange observation is the IRQ allocations seen via /proc/interrupts:
(e.g. eth2 has assigned no less than 12 IRQs !?!)
