DragonFlyBSD

I get this message "smartctl SMART Status not supported: Incomplete response, ATA output registers missing" when trying to use smartctl on SSDs (that don't return that message under Linux for example) using both master and release 5.8.1.

Searching a bit lead me to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191717

So I'm wondering if something could be wrong on DragonFly's side as it seems it was on FreeBSD iscsi driver, though in my case it's not a iscsi disk.

I've ran "smartctl -H -d sat -r ioctl,2 /dev/da0" to compare and I've attached the result, the interesting part is at the end :

REPORT-IOCTL: Device=/dev/da0 Command=SMART STATUS CHECK

REPORT-IOCTL: Device=/dev/da0 Command=SMART STATUS CHECK returned -1 errno=78 [Incomplete response, ATA output registers missing]
SMART Status not supported: Incomplete response, ATA output registers missing

It looks like the answer to the STATUS CHECK command is not taken into account properly.
