--- Comment #5 from Marc marvin24@gmx.de 2010-06-02 10:04:19 PDT --- I donno how many times I rebooted my machine, but now it definitely will die earlier...
here my findings: I kept the userspace patches and tried kernel with and without tiling patches - no change, still crashes. Then I installed a newer distro kernel (maverick backport of 2.6.34, running Ubuntu lucid) -> works.
To make the long story short, crash or not to crash depends on whether plymouth is started or not. Uh! I normaly boot my self compiled kernels with "verbose", while the distro kernels boot with "quiet splash".
I guess plymouth initializes something the ddx doesn't.
