From the feedbacks, the WOL issue has been fixed, and I have submitted a

Great, many thx. I looked for something like that, but failed to find it.

FWIW, a link to the patch submission would have been nice. I tried to
find it just now, but maybe it's not on lore.kernel.org or I did
something stupid. And
https://lists.linuxfoundation.org/pipermail/acpica-devel/ seems to lack
behind or might not be the list you submitted the patch to. Whatever.

The link is here: https://github.com/acpica/acpica/pull/866

There are two kinds of issues in the bug, one is WOL failed in kexec
reboot, another is WOL failed in cold reboot. The former one still exist
after reverted patch(5c62d5aab8752e5ee7bfbe75ed6060db1c787f98),
so this issue is not caused by the reverted patch. The second is caused
by the reverted patch, and has been fixed with my provided patch.

Please see:
https://bugzilla.kernel.org/show_bug.cgi?id=217069#c54
https://bugzilla.kernel.org/show_bug.cgi?id=217069#c59

I'll post a quick update there.

Thx again.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=217069 :

An issue that looked like a network bug was now bisected and it turns
out it's cause by 5c62d5aab875 ("ACPICA: Events: Support fixed PCIe wake
event") which Huacai Chen provided. Could you take a look at the ticket
linked above?

Jianmin did get close to a proper fix a while ago
(https://bugzilla.kernel.org/show_bug.cgi?id=217069#c46 ), but it
appears there wasn't any progress to fix this during the last week. Or
did I miss it?

This is kinda unsatisfying, as the culprit is now known for nearly four
weeks; especially as this is a issue that is present in 6.2 since it was
released and would have been possible to fix there and in mainline with
a simple revert. We even got close to one two weeks ago already
(https://bugzilla.kernel.org/show_bug.cgi?id=217069#c49 ).

#sigh

I'd say we should revert this. Rafael, what's your opinion here?
