RE: [Xen-users] Stop 8E with GPL PV Drivers

Okay, attached is the output from the debug session - looks like there's some more info there.  Also, FYI, the file you uploaded isn't a zip file, it's the actual .sys file.  I kept getting a message about a corrupt archive file and finally used the "file" command on Linux and determined that the zip file wasn't actually a zip file.  I was still able to use it, but just thought I'd let you know.
