Seagate Barracuda ST380817AS has troubles with NCQ. For example,
unpacking a tarball on an XFS filesystem gives this:

ata1.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x2 frozen
ata1.00: cmd 61/40:00:29:a3:98/00:00:00:00:00/40 tag 0 cdb 0x0 data 32768 out
         res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
