Thanks Stefan,

Yes. My understanding is that the issue is because AWS is using older versions
of Xen. They are in the process of updating their fleet to a newer version of
Xen so the change introduced with Stefan's commit isn't an issue any longer.

I think the changes are scheduled to be completed in the next 10-12 weeks. For
now we are carrying a revert in the Fedora Kernel.

You can follow this Fedora CoreOS issue if you'd like to know more about when
the change lands in their backend. We work closely with one of their partner
engineers and he keeps us updated.
