I have three samsung hdds (/sys/block/sda/device/model says SAMSUNG SP2504C)
in a raid configuration.  My system frequently (2-3x/day) experiences
temporary lockups, which produce messages as below in my dmesg/syslog.  The
system recovers, but the hang is annoying to say the least.

Does this drive actually support NCQ? I can't tell from this part of the  log.

I selected that model in part because it at least claimed to support 
NCQ.  I'm not sure if it reflects NCQ or not, but I do have 
/sys/block/sd[abc]/device/queue_{depth,type} which show simple and 31 
respectively.  Samsung's page for the drive also says it supports NCQ:
