Thanks, I'm confident I can fix it up to get it going on my Huawei arm64 D06CS. So that board has a megaraid sas card. In addition, it also has hisi_sas HW, which is another storage controller which we enabled this same feature which is causing the problem. I'll report back when I can. Thanks, john
