Bug#1026965: ACPI Error: Needed [Integer/String/Buffer], found [Package] … (0x3003)

As for Lenovo T14s I manage, it's of type 20T1 (in particular, not the one you linked); its BIOS version is 1.26, released 12/14/2022. The firmware revision is 1.14. No further BIOS upgrade is available for this very laptop as of now. (A new Intel Management Engine Software for Windows has been released three days ago; I'm planning to install it next month and report here if anything changes.)

If you wish to know user-visible problems (rather than the journal-visible problems), there are many; I'm going to report them, too. (One step at a time.)

As of today, the errors and warnings are a tiny bit different:

ACPI Error: Needed [Integer/String/Buffer], found [Package] 00000000e1607619 (20220331/exresop-469)

ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20220331/dswexec-431)

ACPI Error: Aborting method \ADBG due to previous error (AE_AML_OPERAND_TYPE) (20220331/psparse-529)

ACPI Error: Aborting method \_SB.HIDD._DSM due to previous error (AE_AML_OPERAND_TYPE) (20220331/psparse-529)

(the four lines above are red)

ACPI: \_SB_.HIDD: failed to evaluate _DSM b356ecee-4244-8f40-a792-4edd4d758054 (0x3003)

(the line above is orange)

Thanks for the URL https://github.com/fwupd/firmware-lenovo ; I plan to yell there if the next update/upgrade from Lenovo brings no change.

Gratefully,
