Ok, I tested the latest one. It crashes too. Same phenomenon.

I assume the problem lies in the Xen code, not the pvops dom0 kernel.
Should I try a newer version of Xen? (Currently using 4.0.1 from tar-file).

But just to be sure:
 Are there any kernel options which I should NOT use at all?
 (Please take a look at my kernel config in the first post.)

I'm still uncertain about this error message:
 XENBUS: Unable to read cpu state

Are these harmless and can I ignore them? What can be the cause?
Maybe I should disable some of the BIOS options?

Here are some of the options I enabled in the BIOS:
- MPS and ACPI MADT ordering: Modern ordering
- Intel(R) Virtualization Tech: Enabled
- Execute-Disable Bit Capability: Enabled
- Simultaneous Multi-Threading: Enabled
- Intel(R) EIST Technologie: Enabled
- Intel(R) Turbo Boost: Enabled
- C1E Support: Enabled
- Intel(R) C-STATE tech: Enabled
- C State package limit setting: Auto
- C1 Auto Demotion: Enabled
- C3 Auto Demotion: Enabled
- Intel VT-d: Enabled
- Active State Power Managment: Enabled
- Remote Access Configuration: Enabled
- ACPI Aware O/S: Yes
- ACPI APIC support: Enabled
- ACPI Version Features: ACPI v2.0

Any other (further) suggestions?
I'm wondering, because I did not get ANY output at all.
I enabled full debug output, compiled with debug enabled and I
still get nothing...
