Xorg.0.log with active KMS for ATI Radeon X800

Description of problem:
On a current "rawhide" system, locking the screen via "System > Lock Screen" crashes an active running GNOME session provided that (1) KMS is enabled and (2) the chosen screen saver module is an GL based one like "Juggler3D".

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start GNOME session.
2. Set GNOME screensaver theme to "Juggler 3D" or "GL Hanoi".
3. "System > Lock Screen".
Actual results:
GNOME session aborts and leaves the user facing a mouse pointer on top of a black screen.

Expected results:
Screen is locked, and chosen screensaver module sets in.

Additional info:
- Choosing a non-GL screensaver theme allows to lock and unlock the screen
- Adding "nomodeset" to the kernel boot options allows to restore a fully
  functional GNOME screensaver.
- After the GNOME session has aborted, the typical acoustic signal of the
  HV supply of the attached HP A4576A 21" CRT can be heard when switching
  voltage off/on. Then, a mouse pointer appears on top of a black background
  which is first accompanied by the Fedora spinner.
  Switching to a VT seems to work thanks to the acoustic feedback of the
  HV supply but the screen remains entirely black.
  However, typing ctrl-atl-del allows to reboot the system in controlled
- Installed packages include:
  * kernel-2.6.31-0.157.rc6.fc12.x86_64
  * libdrm-2.4.12-0.7.fc12.x86_64
  * mesa-*-7.6-0.8.fc12.x86_64
  * xorg-x11-server-Xorg-1.6.99-35.20090814.fc12.x86_64

Note the last line of Xorg.0.log related to the failed attempt to switch to a working virtual console:

  (WW) xf86CloseConsole: VT_WAITACTIVE failed: Interrupted system call

Comment 3 Joachim Frieben 2009-08-21 05:21:03 UTC
No improvement for latest Koji builds:
- xorg-x11-drv-ati-6.13.0-0.1.20090821gitb1b77a4d6.fc12.x86_64
- xorg-x11-server-Xorg-1.6.99-37.20090820.fc12.x86_64

Xorg.0.log exhibits a trailing line:


without a subsequent backtrace.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue.
