LSI 9311-8i - Constant "attempting task abort" errors

[SeeGee]

I have an LSI 93111-8i flashed with IT firmware R20 with 12x 8TB WD drives attached to a Supermicro Backplane (BPN-SAS3-826EL1). There are two different models of these drives in use: (7x) WD80EZAZ as well as (5x) WD80EDAZ.

 

When I look in the logs, I'm constantly getting errors like this, and it doesn't seem to be specific to either model of drive.

Sometimes they're only a few seconds apart, other times there wont be an entry like this for a few hours, but it IS constant. I'm not sure what this error even means, let alone what to do about it... The array seems to operate without issue in all usage cases, and I have had no problems of any kind as a result of these errors, but they are definitely spamming the logs, and disrupting my "zen thing"... 

 

Any assistance would be appreciated.

did you ever end up fixing this issue? I essentially the same backplane and SAS controller and I have been trying to figure this out for months.
