Re: [Xen-devel] Panic:: handle_irq_event_percpu

Hello Wei,

Result is that using only "1" or "1" in combination with "2" always result in 
SATA I/O errors, so that doesn't boot.

Haven't tried rebooting a lot of times without iommu yet.
(the reason i bought the 890fx board in the first place)
Will try that a few times when i have some more time.
