I'll bet it's the driver - it doesn't feel quite right that a random external command can easily drop drives off the controller, be it smartmontools or mdadm. Thomas, I tried sending a private email to Andy Yan. I haven't got a reply, which kind of isn't surprising in this world of spam. Can I ask you for a referral - could you send him an email asking him if I can have the patch and how to test it? Also, to list-dwellers: I'd greatly appreciate further tips on PCIe SAS HBAs. Thanks!
