Attached.
The lines

(XEN) Local APIC disabled by BIOS -- you can enable it with "lapic"
(XEN) Local APIC not detected. Using dummy APIC emulation

are a bit strange for me. The BIOS is quite simple PheonixBIOS with no options regarding APIC.
lapic kernel parameter was *surely* used


If lapic had been passed on Xen's command line then you would not have got the first line from Xen (the one that ends "...you can enable it with "lapic"").

It seemed strange to me too. But:
$ xm dmesg | grep lapic
(XEN) Local APIC disabled by BIOS -- you can enable it with "lapic"
$ cat /proc/cmdline
lapic root=/dev/hda6 ro console=tty1

Am I missing something?

Btw. I have tried live CDs on the notebook and 2.0.6 works fine (clock runs ok)
but 3.0 is again too fast.
