Created attachment 341211 [details] Xorg.0.log after X server crashes Description of problem: On a fairly old machine (Pentium 1, 200 Mhz, 192 Mb RAM, i430tx mainboard) I installed Fedora 10, because my main computer is damaged. On startx, the X server crashes inside pixman (backtrace attached). Signal thrown is 4 (SIGILL). Updating to latest xorg-x11-server-Xorg and xorg-x11-drv-vesa does not solve the issue. On the main computer (Pentium 4), the same configuration works OK. Version-Release number of selected component (if applicable): pixman-0.12.0-2.fc10.i386 xorg-x11-server-Xorg-1.5.3-15.fc10.i386 xorg-x11-drv-vesa-2.2.0-3.fc10.i386 How reproducible: Always Steps to Reproduce: 1. Get system with Pentium 1 processor 2. Configure xserver with vesa driver 3. Attempt to start xserver by any method. Actual results: The X server starts up, switches to graphics mode, shows the usual B/W pattern, but then shuts down with the attached backtrace. Expected results: The X server should run normally and end up showing graphical desktop. Additional info: I have a copy of freedesktop.org pixman git tree so I am in a position to test updates on demand. I have seen other pixman bug reports here, and this one looks a bit like bugs #451831 and #472000 , except that mine happens right on xserver startup. Not even plain xinit with xterm works.

This bug is already fixed in a later version of pixman, by git commit 1c5de7b05831b3d66821707276b71974a232f5c7 . The corresponding freedesktop report is http://bugs.freedesktop.org/show_bug.cgi?id=17729 and marks it as already fixed. I found this after creating a patch that is equivalent to 1c5de7b05831b3d66821707276b71974a232f5c7 and checking whether current HEAD for pixman still contains the bug. Please update pixman RPM to a later version.
