smartmontools' Automatic Offline Testing fails on sata_sil

[David Liontooth <liontooth@cogweb.net>]

smartmontools Automatic Offline Testing fails on drives connected to a sata_sil controller. 

Bruce Allen, the smartmontools maintainer, suggests the problem may be that the Auto-offline command sticks large values in the ATA sector count register WITHOUT transfering any data. 

Can the sata_sil driver be fixed to accomodate this?

In smartd.conf:

/dev/sdc -d sat -a -o on -S on -s (S/../.././02|L/../../6/03)

Result:

The same model drives work fine with smartmontools cvs on the sata_nv and 3ware 8500 controllers.
