I have been experimenting with various kernel and userland versions this
evening, but without much progress I must add. I can trigger the crash with:

Kernel:

kernel26-git: 2.6.33rc8 as of 20100227

Xorg: (this is what we have in Archlinux atm and the same versions as Michał
posted before):

xorg-apps 7.5-3
xorg-server 1.7.4.901-1
xorg-server-utils 7.5-3
xorg-utils 7.5-1
xorg-xinit 1.2.0-1
xorg-xkb-utils 7.5-2

DRM and drivers:

xf86-video-ati-git 20100217
glproto-git 20100217
driproto-git 20100217
libdrm-git 20100217
mesa-full 20100217

mesa-full is an AUR git package of mesa which provides:
libgl mesa freeglut glut ati-dri intel-dri mach64-dri mga-dri r128-dri
savage-dri tdfx-dri unichrome-dri

Swapping the kernel for an older 2.6.33rc5 version built on 20100126:
... crash!

Swapping other git packages to older versions:

xf86-video-ati-git 20100118
glproto-git 20100206
driproto-git 20100116
libdrm-git 20100118
mesa-full 20100118

and trying different kernels:

kernel26-git 20100227: ... crash!
kernel26-git 20100126: ... crash!

I do not remember having these crashes back in the second half of January so I
wonder if there is something else going on here as well.

Do you all use KDE SC 4.4 and/or Kwin? Do you have these problems with other
window managers as well?

Could it be that the recent builds of KDE have exposed an old bug that was
there all along?
