[Xen-devel] Re: Re: 3ware 9650 and Xen 3.1

["Shaun R." <mailinglists@xxxxxxxxxxxxxxxx>]

ok, i finally got it to boot, i had to do some digging and used the previous 
3ware driver version and it works, not here's the diff of the two... doesnt 
look like too much was changed so i figured i would paste it and see if you 
had a idea about if the problem was with 3wares driver or somthing in the 
xen kernel patch...
