Re: [Xen-devel] FreeBSD/Xen kernel

[Kip Macy <kmacy@xxxxxxxxxxx>]

I've had a large number of downloads, but this is the first bit of
feedback I've gotten. There have been a number of fixes that have gone
into my local tree, so I should post a new binary - although none have
been related to the problem you are seeing.

Are you using an uncompressed copy of the mdroot I posted?
