But I am certain none of these really matter a lot - I got the same
result with all kernels and hypervisors I tried so far since upgrading
to OpenSUSE 11.3. My previous xen hypervisor had no cpuidle or cpufreq
support.

I am not sure what you are referring to here. I have tried different
things. The usual SUSE way is to load processor.ko in the initrd
(INITRD_MODULES="ahci processor" in /etc/sysconfig/kernel).

I'd love to provide it, but I have no serial port. I am considering to
by a docking station to be able to get one.

I don't think so.

Please give me more hints - just hit '0' no Alt-sysrq or anything?
BTW, have you tried at some other platform beside Samsung XS50 laptop?
is it a machine specific issue?
> It could be. Noone else reported anything similar to SUSE. I only saw
it on this laptop.
