Comment (by anonymous):

 Here's a few blockings.. -- This happened very shortly after starting the
 recording, so I'm not 100% sure this is the typical blocking I see, I'll
 post another dump when that comes up.  This has your extra printout and
 this mornings svn version 7830.

 file: linuxis.us/dump3.blocking : Blocking IO is 3/4ths the length down,
 1k lines.

 I'll only post one set of hdparms, since all the settings are identical on
 each drive (I've checked this a dozen times so I know they're synced.

 /dev/hdg:
