From: Andrew Morton <akpm@xxxxxxxx> 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 adds a touch_nmi_watchdog() to the driver's MDELAY macro.
