The catch is: the Oops only occurs with a likelyhood of approx. 60%. I have no idea what introduces this randomness, so it may just be faulty hardware. However, the system is stable if I don't run hald. The same behaviour is also present in kernel 2.6.13.4. I will try to compile a few older kernels later to see whether this is a regression. Anyway I'm attaching Oops output, ksymoops output, and dmesg. I have time to do further debugging if instructed what to do next.
