The patch you're requesting reverts this patch:

PM: ACPI: reboot: Use S5 for reboot
After reboot, it's not possible to use hotkeys to enter BIOS setup
and boot menu on some HP laptops.
BIOS folks identified the root cause is the missing _PTS call, and
BIOS is expecting _PTS to do proper reset.
Using S5 for reboot is default behavior under Windows, "A full
shutdown (S5) occurs when a system restart is requested" [1], so
let's do the same here.

It looks like this was applied to 5.4 and the patch that reverts this
was pulled into 5.13 and later, so that is why 5.4 is the only affected
version. I was confused as to why this wasn't also appearing in Impish
and Jammy. Now we know. So I can close those tasks.

I have observed the following. when I test older kernel
Kernel version Fatal Error
5.4.0-42.46 No
5.4.0-45.49 No
5.4.0-47.51 No
5.4.0-48.52 No
5.4.0-51.56 No
5.4.0-52.57 No
5.4.0-53.59 No
5.4.0-54.60 No
5.4.0-58.64 No
5.4.0-59.65 yes
5.4.0-60.67 yes
later I have bisect kernel between 5.4.0-58.64 and 5.4.0-59.65.
looks like due to the following patch we are observing this issue. The
driver is not handling D3 state properly
PCI/ACPI: Whitelist hotplug ports for D3 if power managed by ACPI
