Xen OS11.1 Dom 0 crash at boot but work fine with OS11.1

I try to run Xen 3 Dom0 OS 11.1 on my PC but i have every times the same problem.

Xen3 Dom0 OS11.1 don’t boot but OS11.1 without Xen boot fine.

I have almost the same error :
ata1.00 exception Emask 0x0 Sact 0x0 Serr 0x0 … frozen

ou

ata1.00 failed to IDENTIFY I/O error …

I have SATA disk with intel ICH6 controleur on MSI915P/G motherboard.

I search everywhere but i find no solution to my problem.

What can you do ?

I try any linux boot parameters like irqpoll, noacpi…
Nothing, i have again the same error (sometimes i have … disable IRQ19 … I/O error …).

Someone can help me ?

THANKS

Now i have spurious IRQ

Nobody have an idea ?

Someone have already this error with xen ?

THANKS
