Hibernate / Suspend Not Working

[ls37]

Hi,

I am having trouble getting my system to hibernate or suspend. I am a Linux newbie, and am running Debian Etch on a Pentium 4 CPU w/ hyperthreading (shows up as 2 CPUs).

When the system tries to go into Hibernate (using Gnome Power Manager), the screen goes black for a moment, then comes back on. However, at this point nothing works when I try to launch any application and I have to restart.

I have checked the /var/log/syslog after this happens, and the sleep process stalls after the line:

"SMP Alternatives: Switching to UP Code"

I have tried some solutions I found by searching internet, among them enabling Frequency Scaling and changing the Frequency Scaling Governor to "Performance" or "Powersave". Neither of these worked.

I also tried switching the sleep mode in BIOS from "S1" to "S3", which changes my "Hibernate" option to "Suspend". When I set the system to Suspend, the exact same thing happens. Changing the Frequency Scaling Governor did not work with this either.

I also tried disabling Hyperthreading in BIOS. I get the same results when trying to Sleep.

I have run out of options that I can think of. Does anyone have any other ideas?

Thanks

Bump. Any suggestions?

This sounds almost exactly like my current problem. I like my comp's suspend-to-RAM feature and use it frequently instead of shutting down.

XP handles it with no problems. I recently (two days ago) installed Debian, so I'm a newbie to the distro, though I've tried various other Linuxes in the past.

When I try to suspend in Debian, it seems to work correctly at first, shutting off the power supply with no indications of problems. It also wakes up properly on either keyboard or mouse activity, and video comes back with no problems.

However, attempting to lauch any programs causes an immediate freeze, though the mouse cursor still moves.

After some 20-30 seconds, the mouse cursor freezes as well and the system becomes completely nonresponsive requiring a hard reset.

I'm a newbie to Linux but this seems to me to be quit like some trouble I got right after installting Fedora 9 on my machine. Linux don't quite act cleanly with 3D accelrated cards like Nvidia an ATI and the system stalls after a while because of the conflicting drivers from Linux while the card suppose a native driver.

I don't know if this applies to youre problem but check out these solutons:
