About ata1:0 problem, as reported in the bugzilla bug: I would try to
disable NCQ to see if it helps. Your disks firmware might not fully
support it.

You can either add the parameter "libata.force=noncq" when loading
your kernel, or set queue_depth to 1 for all the Seagate drives behind
the Marvell MV88SX6081 controller.

About ata5:0 , someone - in user space probably - is trying to do a
SMART ENABLE operation, but the device ignores it. I don't know which
device you are using, but I assume it does not support ATA SMART
feature set. Timeout is an acceptable but not a nice way to answer, a
cancel would have been better; check if there is a firmware upgrade
for your device.

You certainly called the SMART issue, I was wondering why a new distribution install on some older hardware was getting all the errors, clearly the Fedora "smartd" doesn't check SMART capability before trying to enable the feature. Oddly the drive on which I see this does reply to SMART requests, so the firmware must be "semi-functional." Not a problem, in my case the drive is just used for testing handling of hot swap, and has no data of any value.
