Description of problem: When browsing the list of screensavers, follwing message is emitted: [drm:radeon_lock_take] *ERROR* 4 holds heavyweight lock Hardware: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon VE QY on a 2-CPU Dell 450 (with HT enabled -> 4 logical processors). The X server locked once when running a "Boxed" screensaver (the machine was still alive and could be rebooted remotely). Version-Release number of selected component (if applicable): 4.3.0-2 How reproducible: Sometimes Steps to Reproduce: 1. run some OpenGL screensavers. 2. hope to see it, too. Actual Results: Warning messages. Ocassional hangs. Additional info: While this problem is not 100% reproducible, I thought I would file it here to have the issue tracked (I have not found any related report).
Please attach your XFree config file and log file (especially after the lockup and such), and even dmesg (/var/log/messages). Also, does the system hang/lock at all if *no* screen savers are running?
System is _very_ stable when no DRI is involved (well, with RH8.0 there were some problems with USB mice that lead to "keyboard controller jammed" error). The lockup occured after "Apr 15 17:00".

Created attachment 91149 [details] /etc/X11/XF86Config The XFree configuration.
I can confirm this behavior with the same card. I have now moved to 4.3.99.2 (Apr 10) update+RH patches and have not seen it yet.
You have attached your config file however you did not attach the rest of the information requested above. Please attach your X log file from after the lockup, and the complete /var/log/messages file as individual bugzilla attachments. The more information you provide and the greater the detail, the more likelyhood of us being able to determine the problem and possibly fix it. Thanks.

Sorry for the delay but this is a production machine and I am not allowed to play with it whenever I like. The error message "[drm:radeon_lock_take] *ERROR* 4 holds heavyweight lock" has been reproduced by running "Boxed" screensaver demo and switching between windows. The mouse still moved after the lockup but the computer did not react to keyboard or mouse clicks. The lockup was removed by logging in via ssh and killing boxed.
Sounds like a DRM problem.
Can confirm this bug is also evident on a Dell Lattitude 610 notebook, with an ATI Technologies Inc Radeon Mobility M6 LY (rev 0) graphics card. I have had the lockups happening since installing RH9.0 when scrolling through different X screensavers. Updated to kernel 2.4.20-18.9 in case the driver had been fixed, but I find that the machine still locks up. This is a personal laptop, so I am in a position to do some testing if required.
I also find the lockup happens sometimes when the screen saver has been running, that is, without accessing it through Preferences. On moving the mouse, the screen saver goes away, the cursor moves, but I can't select windows, and CTR-ALT-BS or CTL-ALT-F1..F6 or CTL-ALT-DEL don't work. The only recourse is to log in remotely and kill the screen saver process, which is still hanging around.
Same problem here too. Using Dell Lattitude 610 notebook. After installing Ximian Gnome issue got a bit worser.
I get also frequently this error message (and X freeze) when I resize or move a window with a 3D image in it. The faster I do it, the more often it happens.
