>Description:
		It's a continuation of 
		http://www.freebsd.org/cgi/query-pr.cgi?pr=31035.

		The symptoms are the same, just the system is more up to date.
		
		The problem appears as a hang (though a box can be rebooted
		with ctrl-alt-del), after the line of 'Mounting root from 
		ufs:/dev/idad0s1a' appears from the kernel. Only happens if SMP
		is enabled.

		My array controler is: Compaq SMART-2/P array controller, thoug 		it uses the same driver (ida), as the one mentioned in the PR 
		31035.

		Booting with -v as an option doesn't show anything interesting
		after the (well, nothing at all) after the line about mounting 
		root.

>How-To-Repeat:
		Enable SMP on a Proliant 1600 with ida driven array controller.
