Suspend to memory (Fn-Esc) or disk (Fn-A)
causes "divide error" and system hangs.
It needs to be powered down by power button and it
has to fix its disk during boot-up after such procedure.
This is quite unhealthy for the system.
One cannot even disable Fn-A key combination, or lid closing detection.
I have renamed c:\save2dsk.bin to disable saves do disk,
but the system suspends to memory instead and still hangs
with "divide error" after resume.
It is very annoying because I seem to easily hit the
Fn-A key combination trying to hit Ctrl-A.

------------------------------------------------------------------------------
The following was hand-copied from the screen to a piece of paper
(no system feature worked):

I get the following messages on the console:

divide error: 0000
CPU: 0
EIP: 0010: [<00110447>]
EFLAGS: 00010093

Then follow registers, process information, stack, call trace and code.

The system is frozen, nothing works, even Caps-Lock, nor Ctrl-Alt-Del.
Only the Fn combinations work (Fn-a for example).

If I run X-Windows then I have no error on screen,
instead the system just freezes and reacts to
no key presses nor mouse movements.
