Blocktap relies on a Linux kernel patch implementing some AIO functionality 
which is shipped with the xen-unstable distribution.  It sounds like you're 
somehow missing that patch, but I'm not clear how that could have happened.

Where did your Xen install come from?  Compiled yourself, distro kernel, 
or ... ?  Have you made any tweaks to the setup that might be relevant?

Cheers,
Mark
