I have been getting the following error message when booting up ubuntu:
[0.299654] ACPI BIOS Error (bug) Could not resolve symbol [\_SB.PCI0.PB2], AE_NOT_FOUND (20210730/dswload2-162)

System/OS info:
- Ubuntu version: 22.04
- Kernel version: 5.15.0-57-generic
- Device: lenovo legion 7 slim laptop
- CPU: Ryzen 7 5800H
- BIOS Version: LENOVO HACN39WW
I've only tried running sudo apt-get update and sudo apt-get dist-upgrade and this message still persists. The system boots up fine and nothing seems blaringly wrong. I'm just worried this blows up later while i'm using the device.
Note: i'm running ubuntu alongside a windows 10 OS with a dual-boot configuration. [1]: https://i.stack.imgur.com/TXH9h.jpg
