I have two HP Gen10 servers with a lot of drives (and an enclosure) that crashes during the scrub.

It may be the firmware, or a bug in the driver. Or a bug in the hardware.

I’ve disabled scrub there and enable it every time I update the firmware or FreeBSD.
Then it crashes again and I disable it, so the co-worker who is on-call doesn’t get mad at me.
