On the Sony, it looks like it is powered off (hard disc stops, screen
blank, button black). But it is not correctly off. And you can't do
anything, pressing the start button doesn't do anything neither restart.
The only solution, also reported by other people on acpi-devel or swsusp
(I don't remember) is to unplug the battery (and AC). Then, you can plug
the battery again. And pressing the start button will resume correctly.

Nigel reported that patches 97 and 98 were experimental with some S4
features. Patches 99 and 100 corrected the previous bugs (97 and 98) but
you had something to do with ACPI which I did not understand.

You should try the script (just a useful file
/etc/hibernate/hibernate.conf).

I haven't test all features (I have had some problems (but only once
when on my replicator) like sound. But here is a patch for Alsa that you
probably could incorporated. (the swsusp mailing list moved).

Yes! Attached is the diff of a patch Nemaru sent to me off-list, and
I no longer have to do any magic alsactl commands to get sound back
on suspend/resume. Playback still stalls though (just restarting
playback works fine though).

He's sent it to the alsa guys - but if it works for people here, it
may as well be included in the 2.6 swsusp patch in the meantime?

Bernard.
