There is your problem. Looks like there is some sort of an issue
with the cpu driver when the machine is on battery. I am sure that
list members more familiar with CPUPM might have some questions (or
maybe answers, but are there any BIOS settings for CPU frequency
control?

Personally, I figured as much. I was less interested in this issue,
as you had mentioned actually selecting 'Suspend' had no relief.

I suspect that there will be a more useful answer coming soon on how
to get the CPU driver to behave more acceptably.
