Bug 326137 – sys-kernel/gentoo-sources-2.6.32-r7: fails to suspend using pm-suspend and "echo -n mem > /sys/power/state"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Morten Holt 2010-06-29 08:19:12 UTC]

On kernel 2.6.32-gentoo-r7 the system fails to suspend when using either pm-suspend, or when doing "echo -n mem > /sys/power/state".

The system simply flickers for a moment (can be related to problems with my nvidia-drivers and not being able to load console), and then wakes up again. Except that neither mouse nor keyboard work. The numlock and scroll-lock leds are on, and they don't react.
If I plug in a USB keyboard, it will be recognized and works, so system isn't frozen.

It used to work on kernel 2.6.31-gentoo-r10

Reproducible: Always

Steps to Reproduce:
1. Start system
2. As root, run pm-suspend
3.

Actual Results:  
The system wakes up instantly, and keyboard and mouse doesn't work.

Expected Results:  
The system should have gone to sleep.

The issue appears on a freshly booted system, and doesn't seem to be affected by any running software. Also, no USB devices have been plugged in (except the built-in keyboard).

Hi,

You should consider asking for help in forums.g.o, rather than bugs.g.o. Suspend/kernel issues with specific .config don't really belong here, unless the issue having being tracked down to a specific commit/software/etc.

Thanks

Could you please try the latest gentoo-sources?

I am running the newest stable gentoo-sources, do you want me to try the newest unstable?

Yes please

The problem might be fixed on latest kernel sources

Are you using the same .config file?

Does sys-power/hibernate-script works for you?

Problem seems to be fixed with kernel 2.6.34-r1
