(Tried the iso snapshot available today, which is r273635). I lied! That was not the latest snapshot available, my apologies. I = retried with a snapshot from 7 Dec (r275582). In r275582, the LOR when fiddling with /sbin/init is the same as in = 10.1, but the behavior at reboot is different, although it is still = pathological (=93Giving up on 1 buffers=94) . Screenshot: = http://lf.ms/current-r275582-hang-givingup.png I have hit this behavior twice on r275582, but not on 10.1. So something = has changed in CURRENT after r273635, but the basic problem still seems = to be there. --=20 Walter Hop | PGP key: https://lifeforms.nl/pgp
