Hibernate / Suspend Not Working - Gnome Power Manager
I am having trouble getting my system to hibernate or suspend. I'm 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?
