- apm_suspend() and apm_standby() will call splhhigh() before entering
standby or suspend. After resume, the system go back tsleep()ing
in the apm thread without restoring the ipl (this is done in
apm_resume()), and calling tlseep() at IPL_HIGH cause a DIAGNOSTIC
panic (and other bad things, I guess).
Fix by calling apm_resume() from within apm_suspend() or apm_standby(),
after aa_set_powstate() has returned.
- In apm_event_handle(), we test (apm_standbys || apm_suspends) to set
apm_damn_fool_bios to 1 and break the while() loop in apm_periodic_check().
But we set apm_standbys or apm_suspends to non-0 only if apm_op_inprog
is 0 and we failed to record the apm event. With apmd listening
we usually succeed recording the event, so apm_standbys/apm_suspends remains
0 and we never go out of the while() loop.
Fix by apm_op_inprog instead of (apm_standbys || apm_suspends)
to break the loop.
