RE: [Xen-devel] xen problem with save/restore

["Ian Pratt" <m+Ian.Pratt@xxxxxxxxxxxx>]

What were you using before? I seem to recall it was 2.0-testing.bk?

There's currently very few changes between unstable and 2.0-testing
(though this will likely change from next week).  Does it now work
totally reliably? (it failed every time before, right?). You're using
the exact same machine and configuration?
