System fails to suspend to RAM

Hello all,

I just finished upgrading (--update --newuse --deep @world) my Gentoo desktop after leaving it for about a year or so, and for the most part it's working quite nicely. The only problem I can't figure out is why the system just hangs when I try to suspend to RAM. When I try to enter sleep, the system drops to console mode, and after a minute the monitor powers off, but the PC never enters the S3 state. I have to either reset or hit the power.

Here's what updates I know happened in the upgrade:
- kernel: 3.0.3 -> 3.8.5
- nvidia-drivers: 295.95 -> 313.30
- KDE: 4.8.4 -> 4.10.1

I remember having issues with hibernation before, and I remember masking >=x11-drivers/nvidia-drivers-300 at the time. But now that I've upgraded, 295.95 isn't in portage anymore, and I can't go back to test it again.

The motherboard I'm using is fairly old, it's an Asus M2N with an AMD Phenom 9650 X4 CPU.

Does anyone have any suggestions, or possibly know what log files I could start to look at to track this down?

Thanks for any help!

Oh, and my obligatory emerge --info:

I apologize for the somewhat off-topic suggestion, but 4GB of RAM is probably not enough to run without some swap available. Also it is advisable to update much more often than yearly. (Some admins even update daily!) I hope you will find solutions for your main problem also.

For some uses, 4GB is adequate.

OP: Can you reproduce the failure using an untainted kernel?

Thanks for the reply, Hu.

I've tried to get the nouveau driver working but I'm not having any luck. I've made a separate thread on that problem, and will get back to you regarding the sleep issue once that's fixed.

bpoint,

All the ebuilds that were ever in the tree are in the portage attic.
If you want to test, put the ebuild into your local overlay and try to digest it. You may need to fetch the files it wants manually, or you may still have them.

After the digest step works you will be able to emerge it ... but it will not build against kernels 3.7.0 and newer.

Thanks for that info, Neddy!

I've now reverted back to nvidia-drivers-295.59 with gentoo-sources-3.6.11-r2, but sadly trying to sleep still results in the system hanging at a black screen and never entering S3.

At this point, I think the best route would be to revert back to my older 3.0.3 kernel and try again. If that works, then I can start to try newer kernels until I find which one caused sleeping to break.

I am, of course, open to any other suggestions or ideas should anyone have any.

Just a quick update: I tried gentoo-sources-3.0.35 (the oldest available in portage) still with nvidia-drivers-295.59, and my system enters S3 and resumes without a problem.

So, it's looking like a kernel issue. Now I just need to narrow down where it broke...
