Dear Jinsong,

I sent some Infos in November, but they may have got lost on their way
to the mailing list.

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).
> 6. xen/kernel booting serial log
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.
> BTW, is xen still alive when dom0 kernel freeze?
I don't think so.
> If yes, some dump log like key '0'/ 'c'/ 'd'/ 'q' is highly welcomed.
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.
