Not coming back the second time usually means it staggers through the first=

dazed and confused, but not badly enough so that you notice. The second=20
attempt kills it. In this case, I'd go looking for something that plays up=
=20
after the first resume. You might also try some of the hints on the suspend=
2=20
web site, such as trying from init S with minimal modules loaded. (If that=
=20
works, you know it's something loaded later in the boot process that messes=
=20
things up).

If you can't get it to go, try the suspend2 mailing list. I try to be as=20
helpful as I can, and there are tons of users on there with good suggestion=
s=20
and experience you can make use of as well.

Yes. You'll have much better success without DRI in the picture.
