shutdown -p now again works as expected on my Compaq EVO N160 laptop.

But the interrupt storm I still have:

dc0: cmd 3 failed at out byte 1 of 3 
sc0: <System console> at flags 0x100 on isa0

That interrupt storm stuff goes away my using a modified aml
that some kind soul posted for the N160 some months ago.
