Thanks for the replies, all.

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!
