Hi,
I have WalkAbout HammerHead HH3 tablet pc with recent
FreBSD 6.3-PRERELEASE.
This is a PIII-400MHz PC.
I get the following trap when i call apm when one or
both batteries are inserted.
When there are no batteries inserted the following
function doesn't generate a trap.
kernel trap 9 with interrupts disabled
Fatal trap 9: general protection fault while in kernel
mode
instruction pointer = 0x70:0x3a45
stack pointer = 0x28:0xcd32bb60
frame pointer = 0x28:0xcd32bb78
code segment = base 0x00f0000, limit 0xffff, type
0x1b
= DPL 0, pres 1, def32 0, gran 0
processor eflags = resume, IOPL = 0
current process = 968 (apm)
[thread pid 968 tid 100073 ]
Stopped at 0x3a45: *** error reading from address 3a45

This happens /usr/src/usr.sbin/apm/apm.c on line 226:
for (i = 0; i <
aip->ai_batteries; ++i) {
bzero(&aps,
sizeof(aps));
aps.ap_device =
PMDV_BATT0 + i;
if (ioctl(fd,
APMIO_GETPWSTATUS, &aps) == -1)
continue;
printf("Battery
%d:\n", i);
if (aps.ap_batt_flag &
APM_BATT_NOT_PRESENT) {
printf("not
present\n");
continue;
}
in function APM_GETPWSTATUS.
I don't see battery initialization messages in dmesg.
This PC has APM v1.2 only.
Tell me, what else should i check to make APM and
batteries work?
Regards,
Kirill
