Description Stefan Becker 2009-10-04 11:24:43 UTC 
Description of problem:

After bug #522070 was fixed, suspend-to-disk & resume worked nicely. With the latest updates from rawhide it seems the X server crashes after the resume has been completed. When KMS is disabled resume from suspend-to-disk works fine.

Version-Release number of selected component (if applicable):
kernel-2.6.31.1-56.fc12.i686
xorg-x11-drv-ati-6.13.0-0.6.20090929git7968e1fb8.fc12.i686
libdrm-2.4.14-1.fc12.i686
mesa-libGL-7.6-0.13.fc12.i686
xorg-x11-server-Xorg-1.6.99.903-2.fc12.i686

How reproducible:
always

Additional info:

- compared to bug #522070 these parts have changed since then:
kernel-2.6.31.1-48.fc12.i686
xorg-x11-drv-ati-6.13.0-0.4.20090908git651fe5a47.fc12.i686

Unfortunately I don't know the previous xorg-x11-server version

- when I activate hibernate the system switches to a VT and sometimes there is a warning like "unexpected NMI. You must have a HW problem. Trying to continue".

- the resume completes, i.e. I hear the BIOS beep and the sleep LED flashes shortly. After that it should switch to the locked X session screen, but instead after a short while you see X start up again and gdm appears.

- I couldn't see any "crash" messages in /var/log/Xorg.0.log.old or /var/log/messages. So it is only my guess that the X server crashes. When I login into a tty I can see some of my old processes from the previous X session are still active.

- my xorg.conf:

Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
        Option "AccelMethod" "XAA"
EndSection

I have to use "XAA" because of bug #524312

X server log

Retested with the kernel from bug #522070: same problem. So the bug must be in the newer xorg-x11-drv-ati.

There was a driver crash recorded in Xorg.0.log.old but I missed it in my cursory check. See attached log file.

Comment 3 Dave Airlie 2009-10-06 08:40:16 UTC 
can you please retest with latest -ati and X.org server?
Comment 4 Stefan Becker 2009-10-06 11:56:48 UTC 
Needed also latest xorg-x11-server for driver to work correctly. Retested with:

kernel-2.6.31.1-58.fc12.i686
xorg-x11-server-Xorg-1.7.0-1.fc12.i686
xorg-x11-drv-ati-6.13.0-0.7.20091006git457646d73.fc12.i686
libdrm-2.4.14-1.fc12.i686
mesa-libGL-7.6-0.13.fc12.i686

Resume for hibernate seems to work OK again.

But a couple of things I noticed:

 - Option "AccelMethod" "XAA" in xorg.conf seems to be ignored now. Driver uses EXA

 - As far as I can see bug #524312 seems to be fixed, so I wouldn't need XAA anyway any more...

 - Some (KDE) icons are broken with the new driver. Instead of the icon you see a square with random color pixels
