Description of problem:
On a system with P4 (NorthWood-C) with hyperthreading activated and
Intel 865GV chipset I have passed apm=power-off to the kernel to
enable the shutdown of the machine. This causes a kernel panic on boot
with this error message:
Kernel bug at apm.c:1743
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Add "apm=power-off" to the grub image that loads a SMP kernel.
2.Reboot the machine.
3.Select the kernel with "apm=power-off" option.
Actual Results: Kernel Panic
Expected Results: Normal startup and clean shutdown
The PC is an MSI HETIS
I am having the same problem with kernel 2.4.21-15.0.4. Has there
been any progress made?
The machine is a Dell Optiplex GX270 w/ Hyperthreading enabled.
Ingo, could you please pick this up? DaveJ is really swamped with U4.
Does this problem still occur with more recent kernels?
I don't know I sell the machine six month ago because of this bug.

I SOLD the machine six month ago because of this bug.
