System: NetBSD 1.1_ALPHA NetBSD 1.1_ALPHA (FREETOCREATE) #0: Sat Nov 4 19:29:47 EST 1995 amiga
Architecture: amiga

	Back last August Markus Wild(The original amiga port-master)
	pointed out that somehow totally untested code made it's way
        into the kernel	and no one has fixed it.
        Compiling the GENERIC kernel with the option:
        RETINA_SPEED_HACK commented out (the default) results in a kernel
        that vm_faults() immediately
	Just compile a GENERIC kernel and run it on a machine with 
        a retina III card
	Very quick fix that works well and stable is to 
	just uncoment the RETINA_SPEED_HACK    GENERIC kernel option.
        in the sys/arch/amiga/GENERIC file.
	Long term solution would to remove the buggy code
