Description Bruno Wolff III 2008-10-20 14:45:29 EDT
Description of problem:
I am now able to run without setting nomodeset, but am seeing occasional speckled output in firefox windows. Typically a dropdown box, but I did see part of a tab speckled. Shortly after observing one of these I did have X restart. (In the past the crashes lockups required intervention, in this case the restart happened on its own and I had a new gdm screen in less than a minute.) I don't know if that is related or is a seperate problem.

Version-Release number of selected component (if applicable):

How reproducible:
I can't make it happen, but it seems to occur in on the order of minutes when using forms in firefox.

Steps to Reproduce:
Actual results:

If X restarts can you get the /var/log/Xorg.0.log.old and dmesg if possible.

Can you attach a normal Xorg log and dmesg now as well so I can see if I can reproduce.

Xorg.0.log probably from just after the restart

I think this is the Xorg.0.log from the unexpected restart. It has a timestamp from two minutes after the Xorg.0.old which seems close to the correct time. The timestamp on Xorg.0.old corresponds to the last reboot. (I'll be attaching that file next.)

dmesg from same time as previous xorg.log file

I am attaching the dmesg file which has a timestamp that matches (within a minute) that of the first Xorg.0.log file I attached (which is the latest one).

Xorg.0.log after normal reboot

I did a reboot to get normal copies of Xorg.0.log and dmesg. I noticed Xorg.0.log.old had a timestamp from a couple of minutes before Xorg.0.log rather than that of the previous latest Xorg.0.log. I am not sure why that is. I didn't notice X start twice during the reboot and the difference seemed to large. Maybe the file was modified during shutdown.

I'll keep an eye on this, but I think it might be fixed now.
Possibly the mesa update fixed it since I applied it last night and didn't see the problem while waiting to update the ati driver and the kernel. If it reoccurs I'll reopen the bug. Currently I am using:

Bruno, are you sure it is solved? It looks like a duplicate of Bug 466663, and there we agree that the situation has improved, but the problem hasn't been solved yet.
Comment 9 Bruno Wolff III 2008-10-23 16:04:56 EDT
I am not sure they were the same bug. Since I closed this bug I think I have seen odd glyphs for text  two or three times that I didn't feel I knew enough about to open a bug for. The corruption I was seeing before seemed to cover rectangular shapes and was not just messed up glyphs. I haven't seen that reoccur.
I'll add myself as a CC to 466663 and add comments if I see the problem again. There have already been two or three updates to xorg-x11-drv-ati (and some mesa updates) since I last saw the problem so I don't have anything to add right now.
