--- Comment #17 from Roger Pau Monné <royger at freebsd.org> ---
Hello,

Just a wild guess, but could you try to disable indirect descriptors to see if
that makes a difference? AFAIK XenServer block backends don't implement it, but
it doesn't hurt to try. Just add:

hw.xbd.xbd_enable_indirect="0"

To your /boot/loader.conf.

Thanks, Roger.
