There are two types of ACPI errors observed: AE_ALREADY_EXISTS and AE_NOT_FOUND

The former, AE_ALREADY_EXISTS, usually happens

1) when BIOS loads multiple SSDTs (in /sys/firmware/acpi/tables) that contains the objects with the same names (and usually the same functions too). Naming conflicts prevent kernel to load all of them correctly.

2) BIOS's ACPI methods are not serialized and multiple calls the same methods occur.

I would guess we are seeing scenario 1 here. They are usually harmless because a copy of working SSDT is loaded while duplicated ones are discarded.

The later, AE_NOT_FOUND, is the opposite. This occurs when BIOS does NOT load SSDTs and therefore kernel is not able to get information and perform accordingly.

Neither types of error messages can be fixed without BIOS fixes.

Fortunately, all of the failing ACPI methods are optional, and there are good chances that Linux / Ubuntu will work without them. There are three types of devices *might* be affected according to the error messages:

1. USB (\_SB.PCI0.XHC.RHUB...)- but USB ports and devices should just-work without BIOS code, which are usually for OEM customization.

2. Touchpad (\_SB.PCI0.I2Cx...) - error messages are reported for i2c-2 and i2c-3, but it is likely the touchpad is connected to i2c-1. Please check whether you are experience problems with your touchpad.

3. Switchable graphics (\_SB.PCI0.PEG0...)- but error messages are "AE_ALREADY_EXISTS". lspci also shows no discrete VGA present on this system, and nothing to worry about.
