<br>Just to be transparent here, not all possible functionality is tested by
<br>the package maintainers (currently Ian and me) before throwing a new
<br>package into Debian. This is simply not practically feasible for us. [0]
<br>
<br>We rely on the upstream tests to know that the upstream Xen code will
<br>probably work. For Debian specific things, we do test our own use cases,
<br>but e.g. UEFI is not one of them. For this, we rely on active users to
<br>report problems and help solving them. So, yes, things like this can happen.
<br>
<br>Thanks for reporting this. Next step would be to follow Rogers
<br>instructions, and provide config dumps, serial console output etc...
<br>
<br>We're certainly available to include changes / etc to fix things, given
<br>proper information / testing reports from the user. But, the user has to
<br>actively help to make that happen.
