Thinkpad T440, T450, T460 Bios ACPI Errors

Hello,

 

There is an ACPI bug in the bios of the Thinkpad T440 (and T450, T460 according to other users). On Linux it trigger this error at boot :

[    0.086999] ACPI Error: Needed type [Reference], found [Integer] 00000000f7432393 (20180531/exresop-69)
[    0.087026] ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20180531/dswexec-427)
[    0.087042] ACPI Error: Method parse/execution failed \_PR.CPU0._PDC, AE_AML_OPERAND_TYPE (20180531/psparse-516)

It has been confirmed that is a bios bug by Linux Kernel developpers :

https://bugzilla.kernel.org/show_bug.cgi?id=199983

 

It concern also T450 and T460 at least too :

https://bugzilla.redhat.com/show_bug.cgi?id=1458390

 

Can it be fixed please ? Is there a way to report the bug to Lenovo developpers too ?

Thanks !

The same error occurs on a T440s. It does not seem to interfere with the system in any obvious way except for the error message in the kernel output. Still, it would be nice to have a fix.

 

ThinkPad T440s, Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz

Latest BIOS Version: GJETA2WW (2.52), Version ID: GJHT29WW

Kernel: 5.1.9-arch1-1-ARCH

 

ACPI Error: Needed type [Reference], found [Integer] 00000000181f1a2a (20190215/exresop-69)
ACPI Error: AE_AML_OPERAND_TYPE, While resolving operands for [Store] (20190215/dswexec-427)
ACPI Error: Aborting method \_PR.CPU0._PDC due to previous error (AE_AML_OPERAND_TYPE) (20190215/psparse-531)

Would also like to confirm and bump this as an issue with the Thinkpad T440 series. Just updated to the latest available UEFI/BIOS version as well. 

$ sudo dmesg | grep -i acpi\ error
[ 0.336428] ACPI Error: Needed type [Reference], found [Integer] 000000008de14369 (20180810/exresop-69)
