>Description:
	when i enabled softdeps on /var on my alpha, it panics during
	boot. it's not always the same point; sometimes it's during
	dev_mkdb, sometimes in portmap, or whatever.

fatal kernel trap:

    trap entry = 0x2 (memory management fault)
    a0         = 0x3

        pid = 335, comm = portmap

>How-To-Repeat:
	enable softdeps on /var.
	boot alpha.
	watch it panic.
