cz flag

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)

You can also find an image of the error message [here][1]

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
