If I don't supply 'noacpi' option, dom0 kernel crashes with messages 
mentioned in my previous letter. 'noacpi' allows kernel to boot with 
some IRQ issues (only RAID ant network adapters work properly, any other 
onboard PCI device does not work at all).

I will provide it as soon as possible.

- Only with 'noacpi' kernel does not crush. Without it kernel crashes 
with logs I previously attached.
- I deal with this issue in April 2011, when 3.x kernel was not yet 
ready to work as dom0 kernel. Periodically I test new kernel versions 
(3.1, 3.2, 3.3 including 3.3.8), bul all of they are also crashing in 
ACPI initialization. I will try 3.4 kernel as soon as possible.
Thank you for reply!
