>Environment:
NetBSD on Macintosh with ADB based soft power
System: NetBSD stix1.stix.com.au 1.3G NetBSD 1.3G (STIXNCR) #11: Sat Aug 22 13:34:29 EST 1998 weripp@stix1.stix.com.au:/usr/src/sys/arch/mac68k/compile/STIXNCR mac68k


>Description:

Macintoshes whose soft-power is controlled via the direct ADB interface to
not have any delay before power is removed from the system. A small delay is
warrented, to allow the flushing of any hardware disk caches.

>How-To-Repeat:

Corruption could occur during any system shutdown, with certain disks.

>Fix:

The following context diff can be applied to the current version of
/usr/src/sys/arch/dev/adb_direct.c. The delay is the same as that used in
machdep.c.
