New interrupt storm on ioapic0 pin 9 with -current 5.99.11



Hi,

I just updated my -current NetBSD/amd64 workstation, from sources
around April 10, and i not get an interrupt storm (about 60000 / sec)
on ioapic0 pin 9 / CPU0 ... which wasn't there previously.

This problem goes away if i disable either SMP or ACPI.

Any idea ?
