From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i686; Nav) Description of problem: Hardware: Video Accelerator: S3 Savage4 16Mb, AGP2x Monitor: ViewSonic G773 Software: OS: GNU/Linux 2.4.2-2 [dist. RH7.1 "Seawolf" (updates, errata applied using up2date] XF86: 4.0.3 rel 5 (top of /var/log/XF86.0.config indicates that it was compiled on a 2.2.17-8smp) Running Gnome and Sawfish X is hanging/freezing the machine completely for the following three situations:1. When kudzu runs at boot and configures the video card(always) 2. When switching to a console (sometimes) 3. Logging out from gnome by: MainMenu->logout->halt (always) 4. Logging out from gnome by: MainMenu->logout->logout (sometimes) Changes/Actions: 1. Xconfigurator --xpreferxf4 --nodri Also edited /etc/X11/XF86Config and /etc/X11/XF86Config-4 so that the "no_accel" option was activated. Result: case 4 seems not to cause a hang any more. cases 1,2,3 are still a problem. ------------------------------------------------------ 2. Xconfigurator --xpreferxf4 --nodri Left /etc/X11/XF86Config and /etc/X11/XF86Config-4 with "no_accel" commented outso that acceleration should have been taking place Result: case 4 seems not to cause a hang. cases 1,2,3 are still a problem ---------------------------------------------------------- 3. Xconfigurator --xpreferxf3 Cases 1,2,3,4 no longer a problem X uses SVGA server and provides same resolutions without hangs. --------------------------------------------------- I attach my /etc/X11/XF86Config and /etc/X11/XF86Config-4 files. I am sorry that I am unable to provide any strace information but the machine completely hangs and won't let me zap it or soft reset it. My only option is the power switch! TIA. Oisin Feeley (guess Mike Harris will be on this one?!) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Vanilla install RH7.1 on a machine with Diamond Stealth III S540 (Savage 4 chipset) 16MB, AGP2 2 During boot interact with kudzu telling it to configure the video card (give it 1152x840x16bpp) 3.Watch it hang. Then reboot don't interact with kudzu and try to switch consoles with Alt-F2 etc. If that doesn't freeze it then (in gnome) do MainMenu->Logout->Halt Actual Results: Complete system freeze. I left it for up to 2 hours and it was still locked up. Wouldnt zap the Xserver with CTRL-ALT-BS , nor yet reboot the system with CTRL-ALT-DEL Expected Results: Kudzu after saying "I shall now test your Xconfig" should have dropped seamlessly back into the interactive boot. Consoles should have switched. Logout / halt should have happened without hanging the machine. Additional info: Unfortunately there IS no output from the crash!

Created attachment 32699 [details] XF86-4.0.3 XF86Config-4 for Savage4 freeze/crash/hang
This problem should be fixed in the latest XFree86 build. You can obtain XFree86-4.1.0-5 or later from: ftp://people.redhat.com/mharris/testing/bleeding-edge It includes the latest stable Savage driver updates. Does it solve the problem for you? Also be sure you're using our latest kernel erratum which includes some console switching fixes on the kernel side of things.
Hi Mike, The Good News: the XF864.0.5 which was in the bleeding-edge directory at the time of your last post did not solve the problem. I have now installed 4.1.99 from your bleeding-edge directory and the problem is gone. Of course, I have also been using up2date and there have been errata since then. So, problem fixed but I'm not sure why! Thanks for your work on this. The Bad News: I can get XF86 to lock up when I use particular screen savers. Should I open a separate bug report for that?
Yes, all bugs should be filed individually in separate bug reports. Closing bug as fixed in Red Hat Linux 7.3 (XFree86 4.2.0).
