[Xen-users] Re: Major problems with 2.0.7 and SATA drives

[Alexander <alex@xxxxxxxxxx>]

Irqs are not being shared, I just checked:
17:    6039746        Phys-irq  libata
19:          0        Phys-irq  ohci_hcd:usb1, ohci_hcd:usb2 

I actually only have 4 GB of memory, so pae is not necessary and we don't 
want to run 64 bit yet. 

Any other suggestions?
