Dear all,

while switching from 2.6.28(-rc*) to 2.6.29-rc2 S2R is completely hosed
now.

With 2.6.28 I can suspend directly from X and that several times without
problems.

With 2.6.29-rc2 the following symptoms occur:
- when suspending from X screen is shut down, but the computer is still
   running, and it does not react to sysrq
- when suspending from a minimal boot with all modules unloaded it
   suspends fine (the power lamp on my laptop flashes slowly red, that is
   usual and fine), but waking up hangs the computer

It might be related that with 2.6.29-rc2 the intel drm is not activated
due to a buggy KConfig problem that seems still unfixed. But I don't
know if that is important.

Try this: http://bugzilla.kernel.org/show_bug.cgi?id=12495#c2
With the four patches (three linked to directly and the one from bug 12422) I can suspend and resume fine.
