I got the same conclusion you got: it doesn't boot without the MCT
definition. But I'm not asking to change the MCT interface with the
Arch Timer interface (even if I understand it would give faster results
for some usages from the thread Krysztof Kozlowski gave before), I'm just
asking for both. The usage conflict was resolved with the commit
1d80415db64b that prevents the MCT interface from resetting the (same
hardware) timer thus no more disrupting the Arch Timer interface.

The goal is enabling KVM.
