Bug 606142

Just in case it helps, driver seems to be xorg-x11-drv-ati-6.13.0-1.fc13.i686.

After upgrading yesterday some X packages via "yum update" when I start the computer next time, I realize that it crashes every time I start the OS.

So my laptop is totally unusable. I'm going to report this upstream, but I'd need to know how to disable the loading of X server at the start.

The system is totally unusable, so priority should be definitively higher than low.

Thanks for your help,

At least it would be extremely helpful to use the computer in the meantime (I really need to), if you were so kind to explain me how to switch to the radeonhd driver.

does booting with nomodeset help?

Adding the radeon.modeset=0 to the kernel command line seems to work, but I don't know whether crashes are random again.

Setting this bug to needinfo and let us know if it happens again even with nomodeset. Meanwhile, could we get (from running both with and without nomodeset; you can collect the logs even from text mode after Xorg crashes) following logs attached to this bug as separate uncompressed attachments:

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

I'm afraid I haven't expressed myself accurately. The X server crashes when loading the radeon driver, but I'm afraid I'm not able to get to the text mode (unless you have a way to do it). The computer seems to be frozen.

I'm afraid it is not available.

I guess I can do this as normal user after booting the system. Are there any special requirements I should meet?

Thanks for your help,

I'm afraid that crashes are random again, since I removed the radeon.modeset=0 from the grub command line and I have been able to start the X server.

I'm not sure whether this will work, but Alex Deucher suggest a patch for radeon drm (http://bugs.freedesktop.org/show_bug.cgi?id=28821#c4).

Would it be possible to apply it?

Thanks for your help,

Reading https://bugs.freedesktop.org/show_bug.cgi?id=28402, the patch proposed in my previous comment seem to fix the hangs.

Considering that these are system freezes, could you release a patched version soon?

Thanks for your help,

Thanks for the review of this report, Matej.

I forgot to tell that this bugs happens with Fedora 14.

BTW, I don't understand why severity was lowered from “urgent” to “high” (although these would be better labels for priority). The system hangs render the laptop totally unusable and all non-saved work is lost.

Thanks for your help,

This is the third time I experience the system hang in less than four hours use (I don't use my laptop before 16:00).

First, I was using Mozilla, opening a new tab with Ctrl+click. Second, it was mplayer watching a movie. Third was Evolution checking for new messages (which could mess all my mail folders).

Hangs are random not because they are infrequent, but because I cannot explain the cause. And just in case I haven't explained myself clearly, I have to shut down the laptop by cutting the electrical supply (this cannot be good for the computer).

I'm an average user and applying the patch and compiling the kernel myself isn't an easy task for me.

The patch is so simple and specific that it should be harmless.

Sorry for insisting, but three system freezes (and consequential data loss) in less than four hours is too much (at least for me).

Thanks for your help,

I'm not sure this patch is needed on the F14 2.6.35.x kernel, the regression only occured in 2.6.36 from what I can see here.

Thanks for your reply, Dave.

I don't understand your comment, since you added the patch at http://koji.fedoraproject.org/koji/buildinfo?buildID=204223 (among other ones).

I have installed it and I'm experiencing no hangs, but I haven't used the laptop too much. I'll report later if the hangs dissapeared.

Thanks again,


Pablo

As already reported in http://bugs.freedesktop.org/show_bug.cgi?id=28821#c9, I'm not experiencing system hangs, so I think that this bug can be closed.

Just in case I experience a hang again, I'll reopen the bug.

Thanks for your help,
