[PATCH] sata_sil mod15 quirk with Seagate ST3120026AS

From: <stuart@cybertherial.com>

Hardware Environment: AMD64, sil3512 controller on m/b.  Harddrive: Seagate
120GB ST3120026AS

Problem Description: Drive would lock when writing large files, eg video
from firewire, audio editing.  Checked dmesg, was obviously the sata drive.

Have added the drive to the blacklist in sata_sil.c and the problem seems
to have disappeared.

Is there a good test to verify that the mod15 bug is really the problem?
