From 032665a26f5fe230509c4d35bd53f69fb6aa45b0 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 6 Oct 2009 12:27:45 +0000 Subject: Revert "Revert "ide: try to use PIO Mode 0 during probe if possible"" This reverts commit 24df31acaff8465d797f0006437b45ad0f2a5cb1. The root cause of reported system hangs was (now fixed) sis5513 bug and not "ide: try to use PIO Mode 0 during probe if possible" change (commit 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was incorrect (it simply replaced one regression with the other one).
