Hello,
what does the following error mean? Does it mean that my shiny new SSD is
buggy?

It could be.. it means the drive sent the controller a SATA FIS (frame
information structure) it didn't recognize.

hm, if I disable NCQ, I do not get these errors. Maybe OCZ SSD disks should be
blacklisted for NCQ?

They shouldn't be claiming they can do NCQ if so. Can you dump out the
identify data in full (with hdparm) and if possible (or if someone else
with one can comment..) find out whether the same occurs with different
controller types.

Controller reports NCQ queue depth 1.
Did you mean this one?
