with kernel 5.17.x I see ACPI errors on my Lenovo ThinkPad X1 Carbon 6th:
Apr 19 14:39:56 leno kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.RP09.PXSX.TBDU.XHC.RHUB.TPLD], AE_NOT_FOUND (20211217/psargs-330)
Apr 19 14:39:56 leno kernel: ACPI Error: Aborting method \_SB.UBTC.CR01._PLD due to previous error (AE_NOT_FOUND) (20211217/psparse-529)

Any idea what that means ? I could not find ACPI error info related to kernel 5.17. And also no information regarding SB.PCI0.RP09.PXSX.TBDU.XHC.RHUB.TPLD or SB.UBTC.CR01._PLD.
So far I did not experience any malfunction. suspend, hibernate, backlight, etc. is all working.

I ve exactly the same ACPI bug since Kernel 5.17, all firmware module up-to-date even the latest ME firmware 11.8.92.4222, i didn’t notice any change since these ACPI bug message and i don’t know how to explain or resolve them
