I have exactly the same problem, the video never wakes up for acpiconf -s 3. My computer is HP nc8430, with 8.2-PRELEASE amd64. My old laptop Dell Inspiron 1100 with FreeBSD5.5 i386 has the same problem. So FreeBSD just can't handle suspend on my laptops :) On Wed, Dec 1, 2010 at 3:49 PM, David DEMELIER <demelier.david@gmail.com>wrote: > 2010/11/15 Stefan Walter <stefan@freebsd.org>: > > Hi, > > > > I've been using 8.1-RELEASE on this desktop machine for a few months > > already, but only now found the time to look at a couple of problems with > > snd_hda and suspend/resume it still has.
