[Bug 1941657] Re: Server boot failure after adding checks for ACPI IRQ override

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Server boot failure after adding checks for ACPI IRQ override

Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Focal:
Fix Released
Status in linux source package in Hirsute:
Fix Released

Bug description:
SRU Justification:

Impact:

The commit 0ec4e55e9f57 ("ACPI: resources: Add checks for ACPI IRQ
override") introduces regression on some platforms, at least it makes
the UART can't get correct irq setting on two different platforms, and
it makes the kernel can't bootup on these two platforms.

discussion regarding the regression:
https://bugzilla.kernel.org/show_bug.cgi?id=213031#c32


Fix: Revert "ACPI: resources: Add checks for ACPI IRQ override"


Risk: Reverting this patch will keep LP#1909814 ("Keyboard not working") unfixed.
