New Revision: 198049
URL: http://svn.freebsd.org/changeset/base/198049
Log:
Immediately after clearing a pending callout that didn't make it due
to the lock we hold, disable interrupts, and announce to the firmware
that we are shutting down. Especially do this before disabling blocks.
This makes some types of machines with asf enabled no longer hang upon
boot, when we start configuring the interface.
