Hi folks,
even after commit eeb89e2bb1ac ("x86/efi: Load fixmap GDT in
efi_call_phys_epilog()"), my i386/efi qemu boot tests still crash randomly
(roughly 5-10% of the time). As before, I don't see much useful output in
the qemu log (this time it doesn't even complain about a triple fault).

Yeah, the only reason the order was changed was that it seemed more
logical to use the new cr3 to load the GDT. But that was clearly
wrong.
So ack on just changing the or
