Each time I run nvidia-smi on our new compute system I get this type of errors in syslog. Often a few of them in a group:
Feb 25 13:35:02 xxxx kernel: [77419.656602] ACPI BIOS Error (bug): Failure creating named object [\_SB.PC00.PEG1.PEGP._DSM.USRG], AE_ALREADY_EXISTS (20210331/dsfield-184)

The same happens when an snmpd process periodically queries the GPU parameters.
Any ideas why would this be?
The output of nvidia-smi seems to be correct, but I'm a bit puzzled if those syslog errors would matter. I have updated BIOS with the latest version that is only a few days old. Here is the information about the system in question:

The GPU is NVIDIA RTX 3080 10GB. The system is deployed in a server room without monitor, no mouse, no keyboard. The messages show the same way even if I connect monitor/mouse/keyboard. No difference.
I tried to find more information about this problem but no luck. I'm not even sure if it is important to try fixing this or who should I report it to in case it is a genuine bug.
