Description of problem: The X server in Fedora Core 5 (xorg-x11-server-Xorg-1.0.1-9) crashes periodically, with a traceback seeming to originate in FontFileCompleteXLFD. I've captured two tracebacks for the crash, which I will include below. I'm not seeing anything consistent which seems to cause the X server to crash.. I've observed it while working with OpenOffice and while working with Firefox. The most recent crash occurred while I was switching between Metacity workspaces. Again, I don't know that there's any connection. The crash has happened for me a half-dozen times at this point, but I've not seen any consistency in when it happens. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.0.1-9 How reproducible: Unclear. Just use X. Steps to Reproduce: 1. 2. 3. Actual results: Server goes black, all X tasks die, and init restarts X and brings up the Fedora login screen again. Expected results: Additional info: I've been running on the Xen0 kernel recently, but I can't swear that I haven't seen this on the standard kernel.
Created attachment 127476 [details] X Crash traceback, the first This is a crash I had in X yesterday, from start to finish of the X session.
Created attachment 127477 [details] Another X crash, slightly different in the traceback Today's X crash, including everything from the start to finish of the short, happy life of the Xorg server on my box.
The first crash is from a SIGSEGV, which appears to be in the fb layer MMX code. The second crash is a SIGILL, (illegal instruction), which seems like an unrelated issue. Please try to reproduce this without Xen, to determine if it is an issue being caused by running under Xen.
I ran on a non-Xen kernel for a couple of weeks without seeing any X crashes, then ran a bunch of yum updates, and have for the last three days been running on Xen again without yet seeing an X crash. I don't know how I'd try to reproduce this, unfortunately.
