Error while booting in Ubunt 20.04

Question

I am getting this Error while booting into my ubuntu 20.04 version

[   0.241437] ACPI BIOS Error (bug): Could not resolve symbol R_SB.PCIO.P02],
AE_NOT_FOUND (20210730/dswload2-162)

/devinvmelnlp6: clean, 1442061/16251840 files, 46563155/64858880 blocks

It just happened recently (i was not getting it before) It is really annoying and slowing the booting process Can anyone help me? Thanks in advance

No, it always happened but maybe quicly so you didn't notice it before. And no, it doesn't slow the boot process. And, as usual, update UEFI ("BIOS") before anything else. If the messages persist then there's nothing else to do except wait for a kernel update that handles this specific firmware quirks. — ChanganAuto, Jul 14 '22 at 07:33

I have laptop Lenovo V15 G2 ITL.

I have dual boot Ubuntu 20.04 with Windows 11.

I have the same error, that appeared recently, I guess after system update in Ubuntu, maybe a week ago..

I choose advance boot in the grub boot menu, where options are: Ubuntu, with Linux 5.15.0-41-generic Ubuntu, with Linux 5.15.0-41-generic (recovery) Ubuntu, with Linux 5.13.0-52-generic Ubuntu, with Linux 5.13.0-52-generic (recovery)

If I choose Ubuntu, with Linux 5.15.0-41-generic I get described error, but when I choose Ubuntu with Linux 5.13.0-52-generic, system boots without errors.

I guess error has to be with newer/newest kernel.

Ok but after rebooting it returns by default to kernel 5.15.0-41 So I guess you have to choose 5.13.0.52 every single time which which is inconvenient
Is there a possibility for this error to be fixed in the near future? :( — Ahmed Emad, Jul 16 '22 at 18:33

This is a bug in the newest kernel. If you still have the previous kernel, then choose it at boot time and see if the error went away.

To choose the previous kernel press and hold the SHIFT button while booting.

This is not a bug in a kernel. Ubuntu maintainers could hide these mesagges not to disturb users, but still there is nothing to be fixed in a kernel. – Pilot6 Jul 14 '22 at 08:53
@Pilot6: really? https://bugzilla.kernel.org/show_bug.cgi?id=213023 – Frantique Jul 14 '22 at 09:03
It is a matter of opinions. Anyway these messages do not mean much. – Pilot6 Jul 14 '22 at 09:15
how to choose the previous kernel? – Ahmed Emad Jul 14 '22 at 11:36

Confirmed as a kernel bug by that link. – Organic Marble Jul 14 '22 at 11:42
@AhmedEmad: I have updated the answer. – Frantique Jul 14 '22 at 12:00
