It goes away with:
echo 1 > /sys/block/sda/device/queue_depth

I have this problem only with XFS, and even with XFS it goes away
mounting with "nobarrier"...

This last is an interesting datapoint.

I wonder if libata has a generic problem with NCQ + FLUSH CACHE.

What happens if you enable the 'fua' module parameter?  (libata.fua on 
kernel command line, if built in)

it isn't supported here:
sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA

Did you actually try my suggestion?

That message is normal, because libata defaults to FUA==off.

Yes ("libata.fua=1" is ok I think, or it should just be "libata.fua"?):

Is libata built into the kernel, or a module?

If it is a module, using the kernel command line won't work.

built-in, my kernel is pretty monolithic

Yeah, that's pretty suspicious.  Prior to issuing a FLUSH_CACHE op,
one must first drain all outstanding NCQ commands (and not issue new ones).

I'm sure the code must *try* to do that, but perhaps there's a bug in there?
Or just another drive bug?

??

If there was such a bug, the aborted commands list should contain both
FPDMA commands and FLUSH commands.  I don't think command filtering
itself is broken.  Possibly another quirky firmware but it's strange
that this is the only Seagate drive showing this problem.

Thanks.

Yeah, that's the strange bit.

Surely someone at SuSE must have a drive like that,
which they could set up with XFS and reproduce the same results?

I wish we had a detailed hardware catalog.  I'll give a shot at the
internal mailing list.

Thanks.

Or pick up a new one (only about $78 here) and expense it!

Mmm.. $66 for "open box".  But the drive itself has been discontinued by Seagate,
and once claimed to be "World's first SATA desktop drive with NCQ.".

Probably buggy firmware after all.

Couldn't find any in SUSE and I don't think I can't find any vendor who
still carries the drive here.

Yeah, "World's first" is a pretty good clue indicating "broken".
Blacklisting it seems like a good idea after all.

Thanks.

OT: I cannot test anything NCQ related for a while because the Intel
Mobo departed yesterday, so I'm on a different board without NCQ
support  ;)
