Hm, I can reproduce the issue, but I don't understand why it happens.
+EFI and KASAN people, maybe someone has an idea.
This is the guilty patch:
https://github.com/hnaz/linux-mm/commit/7c0265f304de3c3acd02d0015b56a076357bcce3
The issue is only with efi_enter_virtual_mode() AFAIU, not with any of
the other functions.
Thanks!
