Regression with commit 0a67361dcdaa

[Jarkko Nikula]

Hi

v5.7-rc1 hangs in early boot on an Intel Atom based prototype hardware 
while v5.6 boots fine. I bisected the regression into 0a67361dcdaa 
("efi/x86: Remove runtime table address from kexec EFI setup data").

v5.7-rc1 caused a reboot loop on another Intel Core based prototype HW. 
Reboots also on top of 0a67361dcdaa but boots fine with that commit 
reverted.

Our test system uses kexec to boot the test kernel. These two machines 
got regression with v5.7-rc1. We have also others that boot fine.

This should already be fixed in Linus's tree. Please report back
whether that solves your problem or not.

Ah, I forgot to pull & test before bisecting...

Yes, both machines boot fine with the HEAD 00086336a8d9 ("Merge tag 
'efi-urgent-2020-04-15' of 
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip").

OK, good to know. Thanks for confirming.
