HSM violation errors

["Jeff Mitchell" <jeffrey.mitchell@gmail.com>]

I'm seeing errors in dmesg and the like.  It appears to be somewhat
similar to the issue reported here:
http://kerneltrap.org/mailarchive/linux-kernel/2007/8/25/164711 except
that my machine doesn't freeze, and everything seems normal --
hopefully nothing like silent corruption is going on.  Also it's on
brand new hardware...Intel ICH8 mobile chipset with AHCI.  Output from
dmesg, hdparm -I /dev/sda and hdparm --drq-hsm-error /dev/sda is
below...please let me know if there's anything else that would be of
use (and, of course, if this is something I should be worried about
:-)  ).

Thanks.
Jeff
