SMP weirdness in -CURRENT

Is the ACPI module loaded?  John Baldwin recently committed a fix that
allows me to use it again, however, there's a new issue which isn't as
bad as an interrupt storm, but which causes the same problems which you
describe.

Have you tried setting `hw.acpi.force_sci_lo=1' at the loader prompt? 
Maybe you're simply having an interrupt storm.
