For the record: Several of us over on the swsusp list appear to have
rouchly the same problem: With some effort and fiddling (as described in
the previous mail), swsusp2 works for console and even from
unaccelerated X, but whenever DRI ang AGP is enabled it resume will
crash. Some of us think this is related to the agpgart rewrite for
2.6.x, but our patching so far have not made any difference. There seem
to be resume code in the intel-agp plug which we have tried to duplicate
in sis-agp, but it appears not to be called during resume... Obviously,
I don't really know enough about how it is supposed to work so we are
just experimenting for now.

I also seem to have occasional PCMCIA+fan collisions on my ASUS L5800C,
(mentioned earlier on this list) but I don't really thing that is
related, but some things certainly more or less woo-doo... ;-)

HW details and some experiences here:

want more...
