System: NetBSD helix 1.0 NetBSD 1.0 (HELIX) #48: Sun Nov 27 19:46:19 PST 1994 thorpej@helix:/usr/src/sys/arch/hp300/compile/HELIX hp300


>Description:
	The hp300 swapgeneric code requires that both rddriver and sddriver
	be included in the kernel.  This is wrong for any machine which
	may have only hpib or scsi, but would like the capability of
	mounting any disk as root and/or swapping to any disk.

	The problem manifests itself as an undefined symbol
	`sddriver' or `rddriver' when linking the kernel.

>How-To-Repeat:
	Configure only hpib or scsi disks in your kernel and try to use
	swapgeneric.
	
>Fix:
	Apply the following patch to .../hp300/hp300/swapgeneric.c
