Suspend To RAM (S3) - Resume Fails
 

I am running Debian Etch, and have been trying to get "Suspend" to work on my machine. I get the same results whether it is called from Gnome Power Manager after being idle, or if I manually type:

echo "mem" >/sys/power/state

The machine powers down and suspends successfully, but when it resumes, I only get a blank screen. I thought it might be because I am using an NVidia video card, so I tried to suspend from the console after pressing Ctrl+Alt+F1 and then stopping X server and GDM. However, I still get the same blank screen on trying to resume.

The only thing I can do at that point is press the Reset button on my box. I actually have to press it twice to get it to work. Unfortunately, nothing of what happens is saved in syslog or any of the log files after I restart, so I have no way of tracing the problem.

Any advice on what the problem may be?

It also appears that the resume.sh script is not running. I added system beeps to the code before and after it runs each script in the resume.d directory. Upon resuming, lights and fans come on, but no beeps are sounded.
