I upgraded my Ubuntu version from 20.04 to 22.04 (dual boot), and now I get ACPI errors when I boot, but when I load an older kernel version (5.13.0-48-generic), so I only get this errors with the 5.15.0.37-generic.

I saw some solutions where someone suggest to turn ACPI off, but I don't think that's a good solution.

Error messages when booting:

These messages indicate that there are BIOS errors related to power management control and PCI root bridge enumeration data due to an improper ACPI table. While these should not cause problems with regular system operation, they could cause issues with power management functions. Please contact your system vendor and ask for an updated BIOS. See this page for more info.

Since my bios is up-to-date, I have selected kernel version 5.13.0-48 as default and always boot with this. Works without problems and wait for future updates.

This was solved after upgrading the Nouveau drivers to Nvidia-drivers. These errors where showing up on boot and on shutdown, and system was hanging on shutdown. For how to choose the Nvidia drivers for your system see https://askubuntu.com/a/1483375/755271
