From ddccf307a3599e452804e228d8ed30fba578923e Mon Sep 17 00:00:00 2001 From: Reinhard Nissl Date: Thu, 11 Dec 2008 00:31:03 +0100 Subject: [PATCH] [SCSI] mvsas: increase port type detection delay to suit Seagate's 10k6 drive ST3450856SS 0003 I increased the delay step by step until loading of mvsas reliably detected the drive 200 times in sequence. A much better approach would be to monitor the hardware for some flag which indicates that port detection has finished, but I do not have any hardware documentation.
