From 48feb3c419508487becfb9ea3afcc54c3eac6d80 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Tue, 25 Mar 2008 16:50:45 +0800 Subject: ata-acpi: don't call _GTF for disabled drive I got below log after a S3 resume in a ASUS A6VC laptop. The system has only one IDE drive. It appears there is no reason calling _GTF for disabled drive.
