Unable resume from suspend to RAM in AMD E450 laptop

[sling-shot]

I have recently bought a Samsung NP305U1A laptop with AMD E450 APU, Radeon HD 6320 graphics.

Whenever the laptop suspends (automatically or manually) it is unable to resume.
There is no response to any key-press.
Laptop power LED will be blinking in a slow rhythmic manner.

If I press the power button, there is some hard disk activity, power comes on, but display remains switched off.
At this point if I press Ctrl-Alt-Del or Ctrl-Backspace occasionally HDD LED blinks, but the screen NEVER shows any activity.

The only way to shutdown is by longpressing the physical power button, and this results in an immediate poweroff and a file system check on reboot.

There have been some reports of this happening while using AMD graphics driver over at the brown distro forum. They seem to say that it works OK with the open source driver, so the trouble may be with AMD driver.

I have appended a few files thinking that they may give a clue.

While trawling the internet, another user (of another distro) posted that this problem does not occur with fglrx and not open-source ati driver.

So I did a second TEST install and removed fglrx drivers completely.

And... yes, now the netbook suspends and resumes properly.

I hope ATi/AMD fix this thing in a forthcoming driver release.

Is there any workaround for this?

What kernel are you using?  Have you tried a different one to see if that has any effect?

[sling-shot]

3.2.18-pclos2.bfs at present.

Thanks for this idea
I should try 2.6 series. May be it will work better there. But then I have to worry about my Broadcom BCM4313 WiFi too (which already is spotty at best)

You could briefly test the 2.6.38 kernel to see if it allows suspending and recovery correctly.
You don't have to keep using it ....  you can boot into the 3.2.18 kernel afterwards

I have not yet installed 2.6 series kernel.
In the meanwhile, there are some spotty reports of Catalyst 12.8 drivers fixing / not fixing this at phoronix.

My Toshiba laptop sports a Core2Duo T6600 @2.2GHz processor with a Mobility Radeon HD 4650 and never had any problems with Suspend/Hibernate. I'm using the 3.2.18-pclos2.pae.bfs kernel and Catalyst 12.4 proprietary drivers. Do you have the same problems with 12.4?

This isn't just a laptop problem. I suppose most people don't use suspend on desktops, but sometimes it could be useful. And if I try to there is no way of restoring the system. It worked on my last desktop.

But of course it's not that important on desktops.

I use it regularly on my desktop, which is why I have to stick with 2.6.38 kernels ......  none of the later kernels allow this PC to do suspend properly .....  either S2R or S2D

2 things.

1. There is a package called "hibernate" in the repo which is supposed to prepare the computer for this. Has anyone used it?

2. There are 2 versions of kernel in the repo for both 2.6 and 3.2 versions. Why?
kernel-2.6.38.8-pclos1 and kernel-2.6.38.8-pclos3.

The package 'suspend' which is the default on PCLOS I believe, does both S2R and S2D

[sling-shot]

So that rules out a solution with "hibernate"

Also even though I roughly get what is KMS, I do not know what is the exact implications of it.
I believe it will be better for me to go with pclos3 version then.

I've tried downgrading to kernel 2.6.38 on both my 64 bit systems. Suspend still didn't work. (Or actually the suspend part of suspending to RAM appeared to work; reawakening the system didn't.) I suppose I have to test it on my normal 32 bit system tomorrow.  

[sling-shot]

It must have been the video driver. I just tried the 12.9 driver from AMD in my test install and it works. Both suspend and hibernate.
So there is hope yet that once it lands in our repository my laptop will be fully functional.
