RE: [Xen-devel] GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I've only just gotten back to it - I tried upgrading my test machine to
3.3-unstable (Debian package) and it was breaking badly.

Two things I noticed:

1. you are using tap:aio - as a test, can you try using file: instead? I
have never gotten tap:aio working. If you've already tried this and
mentioned it to me then I apologise in advance :)

2. I'm wondering if there might be a race in the code that figures out
if the backend is 32 or 64 bits... I'll do some testing on that.
