I started getting ACPI errors on my Ubuntu 22.10 system, which were not there before.
I saw them on mainline kernel 6.2.2 and Ubuntu kernel 5.19.0 too.
kernel: [ 132.228690] ACPI Error: No handler for Region [RTCM] (0000000097ab3aa0) [SystemCMOS] (20220331/evregion-130)
kernel: [ 132.228697] ACPI Error: Region SystemCMOS (ID=5) has no handler (20220331/exfldio-261)
kernel: [ 132.228701]
kernel: [ 132.228702]
kernel: [ 132.228702] Initialized Local Variables for Method [_GRT]:
kernel: [ 132.228703] Local1: 0000000001457204 <Obj> Integer 0000000000000000
kernel: [ 132.228706]
kernel: [ 132.228707] No Arguments are initialized for method [_GRT]
I do not know how to interpret these.
Can I link those numbers and IDs to a specific device?
There is an RX580 I don’t really use in this system, I could pull, and wonder if it could remove ACPI errors?
Looking up exfldio gives me:
Module Name: exfldio – Aml Field I/O
Whatever that means.
What is Aml? What field?
What does GRT stand for?
What does RTCM stand for?
So many questions… such a dense error.
