Description Frits Letteboer 2004-11-10 13:40:30 UTC 
        Things go wrong when FreeBSD tries to detect devices on the controller (Promise 378
Raid controller):

        ata4-slave: FAILURE - ATA_IDENTIFY timed out
        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
        
        Fault virtual address        = 0x6
        Fault code                = supervisor read, page not present
        Instruction pointer        = 0xffffffff8020683e
        Stack pointer                = 0xffffffff80899ca0
        Frame pointer                = 0xffffff003d9f158
        Code segment                = base rx0, limit 0xfffff, type 0x1b
                                = DPL 0, pres 1, long 1, def32 0, gran 1
        Processor eflags        = interrupt enabled, resume, IOPL = 0
        Current process                = 0 (swapper)
        Trap number                = 12
        Panic: page fault
        Uptime: 27s

Fix: 

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