From 15084a4a63bc300c18b28a8a9afac870c552abce Mon Sep 17 00:00:00 2001 From: Jack Hammer Date: Tue, 24 Jan 2006 14:43:41 -0500 Subject: [PATCH] [SCSI] ips soft lockup during reset/initialization Resetting the adapter causes the ServeRAID driver to exceed the max time allowed by the softlock watchdog. Resetting the hardware can easily require 30 or more seconds. To avoid the "BUG: soft lockup detected on CPU#0!" result, this patch replaces the mdelay() calls in the initialization/reset routines with msleep().
