Hi there,
I'm able to Oops my vanilla 2.6.14 kernel pretty reliably when starting
hald 0.5.4. 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.
Thanks for your help
Felix
