next-20230803: boot hang with serial console enabled

[Aithal, Srikanth]

Hello all,

linux-next build 20230802 onwards seeing host hang issue when booting 
with serial console enabled.



===============
Recreation steps
===============
1. Enable serial console by appending following parameters in grub:

GRUB_CMDLINE_LINUX append with "console=ttyS0,115200n8 earlyprintk"
GRUB_TERMINAL_OUTPUT="console serial"
Update grub.

2. Then try to boot into next-20230802/next-20230803


Below is the error seeing when the host kernel boots and then host hangs.

Should be fixed by
https://lore.kernel.org/all/20230803071034.25571-1-tony@atomide.com/
which Greg seems to have picked up.
