[M76] [fglrx] resume from stand by / hibernate fails on Intrepid 64 on 4GB of RAM

Information on the configuration

Computer Specs: http://eu.computers.toshiba-europe.com/innovation/product/Satellite-A210-16F/135223/
Computer modifications: 4GB RAM, 320 GB HDD
Ubuntu Flavor: Ubuntu Intrepid Ibex (x86-64)
Identically affects: Ubuntu Hardy Heron (x86-64)
Kernel: 2.6.27-9-generic

Information on the problem

Installing the fglrx restricted driver causes the computer to hang after a stand by or hibernate, and demands a hard reboot. X won't display anything, consoles are not accessible, even ssh dies.

After some research I found out that there was a similar problem were people were completely unable to use their desktop when running Ubuntu 64 with fglrx on 4GB of RAM, so I tested with only 2GB of ram (physically and with boot option mem=2G) and stand by (hibernate) works fine. With boot option mem=3G I get the same problematic behavior.

My mtrr table feels wrong (on the fact that it does not display anywhere 256M which I believe is my actual graphics memory), but I don't really know if this has anything to do with the problem or how to properly manipulate it.

I've posted a new version of the -fglrx driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get fglrx 8.620 here:

In intrepid, which is the version which the bug was filed against, the issue is not resolved. By quick testing (meaning just installing and watching what happens) the problem seems to be exactly the same. 2G of RAM everything is fine. 4G never resumes.

In jaunty, again, nothing interesting happens. But it seems to me that in jaunty there is a quite different problem (probably I should file a bug report). Hibernation actually WORKS with both the release fglrx package, and the one provided by the PPA (and the one provided straight by ATI). The problem in jaunty is that suspend resumes to a blank screen ALWAYS. No matter how much ram is installed.

It looks like that the same thing happens to karmic, though to be sure, I have to retest, because my current testing environment is quite a mess.

This is sort of sounding more like a kernel issue so refiling.

Fwiw, since -fglrx is proprietary we cannot backport fixes to the driver to earlier Ubuntu releases.

Bryce,
     Can you confirm this issue exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds.

Thanks in advance.
