Re: Suspend2, cant resume

Well, the title of the thread is a bit misleading: the suspend2 patchset can not modify your ability to suspend to ram (suspension to disk and suspension to ram are two distinct beasts). On the contrary, probably the regression is in the upgrade from 2.6.19 to 2.6.21. I would not mind too much about those warnings in system log, since they are mere debug messages which the newest versions of the suspend2 patchset display.

A possible source of regression (I experienced that too, in the form of a soft lockup when resuming, after the update from 2.6.20 to 2.6.21) are the new tickless and nohz options. In grub configuration, try to add the following boot options to the kernel line: "highres=off nohz=off". Now reboot and see if you are able to resume properly. If this succeeds, I can give you further tips on this (it is a kernel bug and there is a patch).

Re: Suspend2, cant resume

Fine, now you can choose: you can stay without nohz and highres (this is a good solution, they were not there in 2.6.20, thus you can live without them till 2.6.22). Otherwise, I had posted a bug about that and Thomas Gleixner came out with a patch solving it. You can apply it and compile your own kernel. The problem should be solved also in 2.6.22-rc1, but I did not try.
The bug is http://bugzilla.kernel.org/show_bug.cgi?id=8391
You can use the monolothic patch (attachament: collection of pending fixups). I think that these patches break stuff in some other architectures and that the fix applied in 2.6.22-rc1 is slightly different, but you do not need to care about this.
