>Description:
	Things go wrong when FreeBSD tries to detect devices on the controller (Promise 378 Raid controller):

	ata4-slave: FAILURE - ATA_IDENTIFY timed out

	ata4-master: FAILURE - ATA_IDENTIFY timed out
	ata4-master: FAILURE - ATA_IDENTIFY timed out

	ata4-slave: FAILURE - SETFEATURES SET TRANSFER MODE timed out

	Fatal trap 12: page fault while in kernel mode

>How-To-Repeat:
	Enable the controller in BIOS and boot using a GENERIC kernel
