After installing the xen drivers and the catalyst drivers, I rebooted 
windows.
Upon restarting, it went back to the "Configuring Devices n%" screen, 
where it proceeded to crash once again. This time though, the crash 
didn't bring down my entire system. The entire dmesg output is filled 
with "(XEN) AMD-Vi: IO_PAGE_FAULT: domain = 0, device id = 0x0090, fault 
address = 0xffffffc0" (or at least until the terminal buffer). The full 
file is attached. Any thoughts?
