Enable PM_DEBUG? hm, OK. Rafael has been working on fixing the process freezer and it'll take some time to get it to where we want it to be, I expect. Rafael, I think that we could afford to add heaps of debug in there at this stage to help us track down problems like this. Also, it might be useful to add a temporary /proc/freeze-unfreeze thing which will simply do a freeze/unfreeze cycle. Then we can apply various workloads to the machine while madly stressing the freezer code. =
