As noted in comment 4 I use the Xorg defaults. I found that setting nomodeset and Optio "DRI" "off" as per http://fedoraproject.org/wiki/Xorg/Debugging made my system hang.
I have the same problem with my Fedora 14 system running the Mesa Rasterizer on a After reading about changes in the memcpy() implementation of glibc, I am convinced that this is likely caused by the video rasterizer using memcpy() instead of memmove() on overlapping memory regions. I have no idea which software module/package to begin my search... video/graphics is not exactly my speciality. In case it matters, lspci shows my video controller as: 01:00.0 VGA compatible controller: ATI Technologies Inc Broadway XT [Mobility Radeon HD 5800 Series] I hope this helps get this resolved. This "feature" is ... irritating :)

I just reported a similar issue for an Nvidia driver in https://bugzilla.redhat.com/show_bug.cgi?id=743333
This is almost certainly a dupe of #665320. Unfortunately, it doesn't seem like there will be a fix for F14 even though it's rather trivial. The fix is in F15 and can be found here: http://pkgs.fedoraproject.org/gitweb/?p=xorg-x11-server.git;a=commit;h=8e9b95c8071eb5a0ed96fffab156a85e6445a94b
*** Bug 743333 has been marked as a duplicate of this bug. ***
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
