That's strange, I don't think anything has changed in that area recently.

What error code do your disks return? You will probably see some console
output if GEOM has tried to read metadata off the disk and that initial
read fails.
If the drive returns 0x04,0x02 ("Logical unit not ready, initializing cmd.
required"), CAM will attempt to spin the disk up automatically and retry
the command.
