APM oops in 2.1.127

System is RedHat 5.2, kernel 2.1.127. This is a new motherboard with
apm support so I compile it in. The support is recognized based on boot
up messages. The motherboard is a TMC TIVG+ with an MVP3 (82C598AT)
chipset. Processor is an AMD K6-2 at 350MHz. I modified the shutdown
scripts to call halt -p for powerdown after halt. After the "system
halted" message I get a "Power down." message after which is a general
protection fault. Since I'm unsure how to set up the system so it
captures the debugging info after this, I've copied some of it by hand.
I can do a line-by-line copy if it will help run down a debugging
process:

General Protection Fault: f000
EIP 0050: [<00008abb>]

Call trace shows (with hand-correlated symbols from the appropriate
system map:

c010632d (apm_set_power_state)
c0106370 (apm_power_off)
c0107135 (machine_power_off)
c0112b5b (sys_reboot)
c01c325a (tvecs)
c010e6e5 (send_sig_info)
c010e964 (kill_something_info)

Then I get the following message:
Unable to handle kernel paging request at virtual address 00008abb
current->tss.cr3=0193100 %cr3=0193100 (tty_write?)

then I get an oops 0000
EIP 0010: [<0108c43>] (show_registers?)
with most of the same call trace info as before

Suggestions anyone?
