Hi! Here's my latest patchset for suspend to disk on powermac. It also contains a whole bunch of cleanups and fixes in various other places some of which are CCed to Andrew (who will hopefully put them into -mm). Other than that, thanks to the mpic resume/suspend code it appears to work quite well. Thanks to Michael Buesch for testing with PREEMPT enabled which uncovered another bug with cpu "hotplug" (where I still don't understand why the preempt_count is messed up on resume but not when I put a CPU off- and online via sysfs.) To actually get proper suspend for a G5 powermac with an Onyx codec you need to apply the patch at http://patchwork.ozlabs.org/linuxppc/patch?id=8683 Any comments are appreciated, especially on the patch that actually implements the snapshot code ("powermac: suspend to disk on G5.") johannes
