From 19ef9d5e45ce805700f34c248a71a511877b8a5d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 21 May 2008 14:11:24 +0900 Subject: libata: SRST can't be trusted on PMP sil3726 As in sil4726, SRST can't be trusted on sil3726 causing detection problems under certain configuraitons. I thought it was from the Config Disk device but apparently not.
