I'm trying to get sleep and/or hibernate functionality going on a DVR and I'm not sure which power management package to use.

The reason I'm unsure is that I'm running a 2.6.31.5 kernel patched with the airlied drm-next as per the RadeonBuildHowTo over at x.org wiki, and I don't know how that will impact power management stability.

I've searched around and it seems that some people are needing to have video driver modules unload and load on suspend/hibernate and resume because those drivers don't support power management yet, and I'm afraid that the xf86-video-ati-9999 drivers I'm using might be one of them.

So, I'm hoping someone here has already gone through what I'm doing, and can offer some advice on which package is the best to use for me. Will either one work properly and safely with a kernel setup like mine?

Moved from Kernel & Hardware to Unsupported Software.

(@pilla: sorry bout that. just saw "power management" in the description and jumped right in there.)


OK, I've finally been able to locate some docs on pm-utils, and understand now that pm-utils can be a wrapper around toi, swsusp or whatever pm support is in use. So I guess this thread should have been called: "SWSusp et.al. Vs. TuxOnIce".

Has anyone here patched toi into a kernel 2.6.31.5 that's already been patched with airlied's drm-next? I only got drm-next patched into vanilla sources 2.6.31.5 by following the instructions in the radeon-build-how-to at x.org, so I'm certainly no old hat at patching kernels. I'm reading through the docs on patching the kernel, but advice about any gotcha's to look out for in my situation would be greatly appreciated.

I'm especially interested in hearing about anyone's experiences doing this for a system with the same ATI graphics chipset (see below) and drivers (xf86-video-ati-9999). Especially whether suspend/hibernate can be safely used at all with those drivers/chipsets (No sense in doing something that's known to not work).

I've put ToI on the back burner for now and I'm just focusing on doing things with the kernels' existing swsusp feature.

Of course, that isn't the end of things... I can only get the wakeup alarm to work if I set the alarm then sleep the system and immediately wake it up manually by pressing a key on the keyboard, then putting the system to sleep again. After all that it will wake up at the alarm time I set.

Has anyone run into (and hopefully solved :) ) this problem before?
