Description Leonid Isaev 2010-10-21 14:54:35 UTC

After opening some web pages in firefox, the GPU will completely lockup, followed by the system freeze, while the screen shows artifacts (in my case it is slowly turning white). Here are the details:

* uname -a

This happens, if I try to browse, for instance, to http://www.ph.utexas.edu/~macdgrp/ (works in links).

I cannot reproduce it here - Mandriva Linux Cooker, KMS:

{{{
shlomif:~$ uname -a 
Linux telaviv1.shlomifish.org 2.6.36-desktop-0.rc8.1.1mnb #1 SMP Sat Oct 16 06:20:05 CEST 2010 i686 i686 i386 GNU/Linux
shlomif:~$ lspcidrake -v | grep VGA
Card:ATI Radeon HD 2000 and later (radeon/fglrx): ATI Technologies Inc|RV630 PRO AGP [Radeon HD 2600 PRO AGP] [DISPLAY_VGA] (vendor:1002 device:9587 subv:18bc subd:0028)
}}}

Seems like that page has a large image which is scaled down by the browser and placed on the page, instead of being resized. Maybe that's the cause of the problem.

After more testing, it seems, that my bug report is a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=30645, although, the symptoms are sometimes different.

Shlomi, in the above report there is a link to a very large (~4MB) image, which always locks my radeon GPU, but Nvidia (nouveau) is OK. There is also an indication (see the last post) that 2.6.36rc8 fixes the bug. Can you confirm this?
I am on 2.6.35.7... just haven't yet got time to build .36.

Leonid.
