Hello,

while compiling a new one, i caught a bug caused by ACPI or rather TPM.

[    0.234262] ACPI BIOS Error (bug): Could not resolve symbol
[\_SB.PCI0.GPP0.SWUS.SWDS], AE_NOT_FOUND (20211217/dswload2-162)

What's the bug exactly?

ACPI related warnings are normally pretty innocuous.

Hi Artem,

thanks for answer. I guess its a BIOS issued alert and if i disable TPM security alert will turn off. Thanks.
