It seems that macppc snapshots are broken on this model. The RAMDISK kernel never reaches userland, it gets as far as mounting root (root on rd0a..) and then.. stops.
Unfortunately, I'm not sure when this started, I haven't powered on this system since I moved.. my bad. :-) USB device insertions/removals continue making noise, so, it's not completely dead. No problems with release, dmesg attached. -Bryan. Copyright (c) 1982, 1986, 1989, 1991, 1993 The Regents of the University of California, All rights reserved. Copyright (c) 1995-2012 OpenBSD.
