Hi!
No, I do not actively search for lockup bugs, but they seem to search me ;).
martin@shambhala:~> cat /proc/version Linux version 2.6.38-rc7-tp42-00142-g212e349 (martin@shambhala) (gcc version 4.4.5 (Debian 4.4.5-11) ) #4 PREEMPT Sat Mar 5 12:03:41 CET 2011
locks up hard when using desktop cube of kwin from KDE 4.5.1.
It happens within a few seconds to about 30 seconds after activating the effect with Ctrl-F11. Otherwise the machine seems to work fine so far - if that continues I do not have much of a problem with the bug since I do not use desktop cube other than for getting a feel of compositing performance. Effects seem to be more fluent, more smooth anyway, I guess due to Radeon KMS page flipping.
I am using X.org 1.9.4 with Radeon driver 1:6.14.0-1 on Debian Wheezy/Sid/Experimental on a ThinkPad T42 with:
martin@shambhala:~> lspci -nn | grep VGA 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] [1002:4e50]
This didn't happen with 2.6.37-tp42-rtime-00004-g9eb63ce, same gcc.
Did you also update your ddx or mesa during this period? It might also be a issue in the userspace acceleration drivers. Are you using the r300 classic or r300 gallium 3D driver?
Debian maintainers activated the gallium one in the meantime:
martin@shambhala:~> glxinfo | grep OpenGL OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RV350 OpenGL version string: 2.1 Mesa 7.10 OpenGL shading language version string: 1.20 OpenGL extensions:
I think I tried the desktop cube with the gallium one already, but I am not absolutely sure.
I have a 2.6.37 kernel still at hand and will test with just changing the kernel.
Thanks,
