From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041020 Description of problem: After trial and error, I realized that X will become unstable and crash the computer after a while (during a normal day's use) if I have 2 DIMMs installed. memtest86 says that memory is good. Others on x.org have reported similar, but it hasn't been obvious that the DIMM configuration makes an impact until recently. Bios version is the latest (1014). I've swapped DIMMs to make sure one isn't bad. (Still testing, but so far so good.) My baseline test is to use the screensaver XFlame and let the computer sit overnight. It has never survived the night without being frozen in the morning if both DIMMs are installed. Choosing 'blank screen' instead of a screen saver seems to avoid the problem, so that's why I list this as a problem in the xorg-x11 package. However, crashes and stability problems arise during normal interactive use, even if 'blank screen' is selected. Version-Release number of selected component (if applicable): xorg-x11-6.8.1-12.FC3.21 How reproducible: Always Steps to Reproduce: 1.Install 2 Asus 'qualified' DIMMS in Dual-channel configuration (I'm using two Transcend 512MB DIMMs) 2.Boot the machine normally into X 3.Choose the XFlame screensaver, perhaps launch a few apps (like Mozilla) 4.Let the screen saver sit overnight Actual Results: Computer frozen by morning. During normal use, apps may segfault, X may restart spotaniously, the kernel may panic (keyboard lights blinking), computer locks up hard, etc. Most evident during clicks, scrolling, workspace changes, etc. Expected Results: No crashes, panics, unusual app failures, etc. Additional info: The top of /var/log/Xorg.0.log says: X Window System Version 6.8.1 Release Date: 17 September 2004 X Protocol Version 11, Revision 0, Release 6.8.1 Build Operating System: Linux 2.6.9-1.751_ELsmp i686 [ELF] Current Operating System: Linux DrTheopolis.netroedge.com 2.6.10-1.760_FC3smp #1 SMP Wed Feb 2 00:29:03 EST 2005 i686 Build Date: 01 December 2004 Build Host: tweety.build.redhat.com Module Loader present OS Kernel: Linux version 2.6.10-1.760_FC3smp (bhcompile.redhat.com) (gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)) #1 SMP Wed Feb 2 00:29:03 EST 2005 Also, see the related x.org bugzilla entry: https://bugs.freedesktop.org/show_bug.cgi?id=1771 And, (marked as dup): https://bugs.freedesktop.org/show_bug.cgi?id=2136
