Architecture: sparc64
Machine: sparc64
>Description:
	When booting a sparc64 kernel with LFS on root (the bootblocks
	and kernel need to be loaded from an FFS partition and the
	root filesystem specified with 'boot -a') the root partition
	device in /dev cannot be accessed - it gives 'Bad file descriptor'.

	Netbooting the bootblocks and kernel and specifying the
	root partition as sd0e results in fsck panicing with:

            Stopped in pid 9.1 (fsck) at sys_statfs+0x54: ldx [%i0 + 0 x10], %o0
            db> trace
            syscall(1133bed0, 9d, 0, 112f1300, 4052fb78, 4052fb74) at
            syscall+0x344
            syscall_setup(ffffffffffffdc6d, ffffffffffffcbf0, 212000, 406e0a80,
            0, 0) at syscall_setup+0xe8

        Netbooting with nfs root and mounting sd0e somewhere else works fine.

>How-To-Repeat:
	eg: create LFS sd0e and boot it as root filesystem
            # fsck
            /dev/sd0e (Bad file descriptor)Can't stat /dev/sd0e
            /dev/sd0e (Bad file descriptor)Can't stat /dev/sd0e
            Can't stat /dev/sd0e: Bad file descriptor
            ** /dev/rsd0a
            ** File system is clean; not checking
            # ls -l /dev/sd0*
            ls: /dev/sd0e: Bad file descriptor
