>Environment:
System: NetBSD sasha 4.99.50 NetBSD 4.99.50 (Nocturno-nodbg) #229: Fri Jan 25 22:38:40 CET 2008 juan@sasha:/home/juan/build/i386/obj/sys/arch/i386/compile/Nocturno-nodbg i386
Architecture: i386
Machine: i386
>Description:
	While debugging another unrelated problem, I've found that my
	system fails before that the point I wanted to check. Looks like
	that ahcisata1 is the culprit and triggers the TAILQ_INSERT_TAIL
	check with QUEUDEBUG.

	dmesg available at: http://www.xtrarom.org/~juan/dmesg-sasha.txt

>How-To-Repeat:
	Boot a kernel with QUEUEDEBUG and an AHCI controller
>Fix:
	Yes, please.
