Andrew: thanks for isolating this problem.
Tejun: any thoughts? The STRANGE_BUFFER_LENGTH problem is fixed in the
code that Andrew is running. The problem is provoked with '-o on' which
goes via a TASKFILE ioctl.
Cheers,
Bruce

It appears to be the '-o on' causing the problem. If I remove that,
the errors go away. The strange part is that according to the smartctl
documentation, my drives support it:

Does removing '-o on' and/or '-S on' eliminate the errors?

Bruce,
Just built it -- it eliminated the HSM violations, but I still get the
device errors:
smartmontools release 5.38 dated 2006/12/20 at 20:37:59 UTC
(I see the above date, even though I verified it is built from CVS head)
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

This is what it is in smartd.conf:
/dev/sda -d ata -a -o on -S on
/dev/sdb -d ata -a -o on -S on
/dev/sdc -d ata -a -o on -S on
Thanks, -Andrew
