Hrm, I don't seem to be able to reproduce this with an installation
built from sources and also can't remember a commit between BETA3 and
BETA4 which should be able to cause this. I currently can't test the
10-BETA4 install image, though. Was the machine in question running
FreeBSD before, i. e. is it known good hardware? Did savecore eventually
succeed on writing out a dump?
