smartd definitely gives something to the device which it does not
like.
Initially I thought perhaps TEST_UNIT_READY should not be allowed to
disconnect just like INQUIRY and REQUEST_SENSE commands. But what
we're seeing aborted here is a TEST_UNIT_READY presumably submitted by
the scsi-midlayer after the ABORT attempt.
Let's see what the heck smartd is sending to the device. Please
reboot with smartd enabled and post the logs that get output
from this patch below applied, thanks.
