Hi all,


I've got some problem when booting mips32.


I got a No.23 trap when calling start_kernel --->  local_irq_enable :


irq 23, desc: 802a98a0, depth: 1, count: 0, unhandled: 0
->handle_irq():  80148c6c, handle_bad_irq+0x0/0x2b4
->chip(): 8029f738, 0x8029f738
->action(): 00000000
  IRQ_DISABLED set
unexpected IRQ # 23



IRQ != c0_cause.ExcCode

You should look up your kernel's IRQ to interrupt source mapping to see what is connected to IRQ 23.
