I am noticing cascading errors when using containers that move a lot of data (sabnzbd, firefox downloading, tdarr) that present as system hangs and dropped connectivity.  The error in the log is:

`May 31 10:23:23 NAS846 kernel: ACPI BIOS Error (bug): Failure creating named object [\_SB.PC00.PEG1.PEGP._DSM.USRG], AE_ALREADY_EXISTS (20220331/dsfield-184)
May 31 10:23:23 NAS846 kernel: ACPI Error: AE_ALREADY_EXISTS, CreateBufferField failure (20220331/dswload2-477)
May 31 10:23:23 NAS846 kernel: ACPI Error: Aborting method \_SB.PC00.PEG1.PEGP._DSM due to previous error (AE_ALREADY_EXISTS) (20220331/psparse-529)`

 

I am on the latest bios and latest drivers for my GPU.

Okay, it looks like this is a red herring.  I removed the GPU and that got this error to stop happening, but the symptoms are still there.  If I purposely throttle sabnzbd down to 10MB/s, that seems to keep things stable, but still an issue.

another datapoint

it is also having this issue on array-to-cache data transfers as well

Post new diags to see if there's anything there since previous one were spammed with that error.
