Forgot to mention. I runned memtest for 6 passes without any problems reported. My CPU is not overclocked and I just underclocked it for testing purposes. No luck :| I will start testing the temperature and voltages as well, just to make sure there are no shortages. <div class="gmail_quote">On Wed, Jun 18, 2008 at 9:37 PM, Daniel Stone <<a href="mailto:daniel@fooishbar.org">daniel@fooishbar.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">On Wed, Jun 18, 2008 at 09:24:30PM +0200, Michael v.Vierssen wrote: > I've done the following: > > - Using the NV driver instead of the closed NVidia driver. > Not tainting the kernel in any way and 3D acceleration disabled. > - Getting a backtrace of Metacity segfaulting.

And where should I look next? </div>Yeah, at this point I'd suggest just running memtest86 and some other tools like that to determine basic system health. This looks completely random. Is your system overheating? Is your CPU overclocked?
