Hi there, I have been using my laptop (Dell Inspiron 6400 with an ATI Mobility X1400 [lspci info below]) with the radeonhd driver without no problems. After I switched to Ubuntu 10.04 first and then to Fedora 13, those distributions came with the radeon driver default and I began to experience random crashes at system start when the video driver was loaded (reported at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/584525 and https://bugzilla.redhat.com/show_bug.cgi?id=606142). Yesterday I updated some packages via the Fedora updater (yum install) and the crash happens each time I start the system. So the laptop is totally unusable (I'm reporting this using the Fedora 13 in live mode). I don't even know how to disable the X server loading (I have googled for it, but I found nothing). The xorg.conf file seems not to be part of Fedora (http://fedoraforum.org/forum/showthread.php?t=20492), so I cannot provide it, and no X.0.log is provided. After reading http://fedoraproject.org/wiki/Xorg/Debugging, I guess I need a PhD in computer science to report it. I'll try to switch to the radeonhd driver and see whether I could find a way to report this crash (although it is extremely complicated for me [I'm a user, not a programer]). Thanks anyway.

Does booting into ums mode work? Add radeon.modeset=0 to the kernel command line in grub.
Thanks, Alex, for your reply. Adding radeon.modeset=0 to grub seemed to work, but I'm not sure whether crashes are random again. Thanks for your help, Pablo
I'm afraid that radeon.modeset=0 doesn't work with Fedora 14 (the X server won't be loaded with this option). Is there any workaround? BTW, I have experienced another computer freeze when watching a streamed video. Is there any way I can get a log to report? Thanks for your help, Pablo
How much vram does your system have? This patch may help: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=b7d8cce5b558e0c0aa6898c9865356481598b46d

RAM is 2GB, but I don't know how much vram does the laptop have. > This patch may help: > http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=b7d8cce5b558e0c0aa6898c9865356481598b46d Thanks for your help, but what is this patch for? I mean, does it enable radeon.modeset=0 or does it prevent system freezes? Many thanks, Pablo

Patch has no effect with modeset=0. Thanks for your reply and for the patch, Alex. Reading https://bugs.freedesktop.org/show_bug.cgi?id=28402, I guess this patch will fix my random crashes. Thanks again, Pablo
Did the patch fixed your issue ?
(In reply to comment #8) > Did the patch fixed your issue ? As I reported at https://bugzilla.redhat.com/show_bug.cgi?id=606142#c19, I installed a patched kernel four days ago and I haven't experienced a system hang since then. I tend to think that the bug has been fixed by this patch. But since those system hangs are random, I cannot say that the bug has been fixed at all. I guess that waiting a week or a couple of weeks more would be a better option to check whether this bug can be closed. Thanks for your help, Pablo
I am closing the bug now as otherwise i or you will forget about it, if you hit the lockup again reopen (less change you forget to reopn if you hit the bug again ;)).
