Saw that popping up in my log today on a brand new T61 thinkpad:

Kernel recovered just fine and things seem smooth so far. Is that something I need
to worry about ?

Please post the result of 'hdparm -I /dev/sda' and you don't need to
worry about it too much.

Allright. What is happening exactly ? A fluke on the link ?

The drive is sending spurious completions of NCQ commands (ie. it's
sending completions for commands which are not pending). We believe
this happens due to firmware bugs and it matched the reality pretty well
(drives with spurious completions usually had other NCQ related
problems) but recently too many new drives are causing this problem. I
have no idea what's going on. I guess it's about time to contact
harddrive vendors.
