Although turning off apm works, this is a fix to the symptom and not a

apm_bios_call_simple calls local_save_flags and afterwards
raw_lock_irq_restore is then called. Shouldn't that have been
raw_local_save_flags?
ah, indeed. I fixed this bug and have uploaded the -50-26 patch.
Chuck, does this fix the APM problems for you?
i've also uploaded -50-27 in which i've improved the irq-flags debugging
code. They are activated if CONFIG_DEBUG_PREEMPT is enabled, and can
come in two variants of kernel messages:
BUG: bad raw irq-flag value 80000000, test/3810!
BUG: bad soft irq-flag value 00000202, test/3810!
so we should now be able to detect mismatches of irq flags right where
they occur.

Ack!! I didn't have that enabled so I am rebuilding again. One thing I've
noticed is that sox seems to be hanging when it is trying to play a .wav
file (for system beeps) and there aren't any error messages about what
might be going on.
