>Organization:
>Environment:
System: NetBSD/emips 5.99.52 around 20110612 on Microsoft Giano on Windows XP
Architecture: mipseb
Machine: emips
>Description:
NetBSD/emips GENERIC kernel hangs right after interrupts are enabled.
It spins in cpu_intr() because splintr() returns ipending==MIPS_INT_MASK_5
while no interrupts are asserted in TheAic->IrqStatus in emips_aic_intr().

5.99.44 GENERIC kernel around 20110130 worked fine.

>How-To-Repeat:
Boot -current NetBSD/emips GENERIC kernel on Microsoft Giano.

>Fix:
Unknown.
