package with all debug information

With Kernel 2.6.33-rc7 and xf86-video-ati GIT d9af6d, everything works perfectly - unless I try to start mozilla thunderbird or filezilla. At the moment the applications creates its window the GPU stalls (recognizable by "fade to white" effect on the screen). Attached files are dmesg (shows nothing), Xorg.0.log (shows nothing) and all files in /sys/kernel/debug/dri, machine is fully usable except for gfx card/keyboard/mouse.
Comment 1 Christian Schmidt 2010-02-09 10:32:24 UTC 
More tested kernels with the same impact:

2.6.32.4, 2.6.32.8, 2.6.33-rc1, 2.6.33-rc4, 2.6.33-rc6

New tests: Kernel 2.6.33-gb979b2c (from git://git.kernel.org/pub/scm/linux/kernel/git/glisse/drm-radeon.git), ddx 6.12.191 (GIT as of 2010-03-12). No errors or warnings in dmesg, only (possibly) interesting messages in Xorg.0.log are

Procedure to get KMS: 
rmmod radeon; modprobe radeon modeset=1 dynpm=0 dynclks=0

Radeon module is initially loaded with modeset=0.

The machine in question here is a Lenovo ThinkPad T500, Type 2082-7SG.
Comment 7 Alex Deucher 2010-10-19 19:15:46 UTC 
Is this still an issue with a newer version of the kernel or driver?
