My 3.1-STable box. make world'ed 2 days ago.
FreeBSD btl.42.org 3.1-STABLE FreeBSD 3.1-STABLE #0: Tue Mar 23 02:25:33 CET 1999 sec@btl.42.org:/usr/src/sys/compile/BTL i386
>Description:
on 2.2.6 I applied the apm_poweroff patch, and my box would power off on
"halt -p" without problem.
This is what i used on 2.2.6:

/* APM Battery low handler */

now on 3.1 (where the code is already there) it doesn't work anymore.
I added a few debug statements liek that:
/*
* Turn off the entire system.
*/
static void
apm_power_off(int howto, void *junk)
{
u_long eax, ebx, ecx, edx;
printf("trying to shutdown\n");
/* Not halting powering off, or not active */
if (!(howto & RB_POWEROFF) || !apm_softc.active)
return;
eax = (APM_BIOS << 8) | APM_SETPWSTATE;
ebx = PMDV_ALLDEV;
ecx = PMST_OFF;
edx = 0;
printf("actually trying to shutdown\n");
if(apm_int(&eax, &ebx, &ecx, &edx))
printf("Entire system shutdown failure: errcode = %ld\n",
0xff & (eax >> 8));
}
and all I get on 'halt -p' is:
syncing disks... 10 10 done
trying to shutdown
actually trying to shutdown
Entire system shutdown failure: errcode = 96
The operating system has halted.
Plese press any key to reboot.
