In 2.1.40, the APM power down on system halt does not work as one would
expect, it has to be done manually. With both CONFIG_APM and
CONFIG_APM_POWER_OFF enabled, 2.0.30 switches power off on system halt
automatically.
Whats the philosophy behind making a difference between
LINUX_REBOOT_CMD_POWER_OFF and LINUX_REBOOT_CMD_HALT with APM ?
I tried the following patch:
diff -urN linux-2.1.40.orig/kernel/sys.c
