BTW, why isn't stuff like this not catched during next or at least
before the final release? Is nothing running CI on upstream with all
that XEN muck active?

This problem showed up by not being able to start the X server (probably
not the freshest one) in dom0 on a moderate aged AMD system.

Our CI tests tend do be more text console based for dom0.

tools/testing/selftests/x86/io[perm|pl] should have caught that as well,
right? If not, we need to fix the selftests.

Hmm, yes. Thanks for the pointer.

Will ask our testing specialist what is done in this regard and how it
can be enhanced.
