After kernel 2.6.21, the qemu of mips with nfsroot is not working. There are too much WATCHDOG timeout. I try to find what makes it not working and I found it. After Ingo Monlar's patch "[PATCH] genirq: do not mask interrupts by default" [1], it's not working. To solve this, we also have to register the IRQ disable field in MIPS, as x86 does.
