Comment 2 for bug 579167

I „fixed“ the crashes for a little while with changing to the open source radeon driver. It ran almost perfectly however with all the artifacts and undrawn shadows it was unplayable.

A few days later I cobbled together a fix.

And this worked for a few hours until it hung again. I have already also done a memory test and a hard disk test. (Using „memtest“ and „MHDD“ respectively) Everything seems to be in order but my box still locks up.
