State-Changed-Why: 
Wouter,

can you please provide us a backtrace from a kernel dump?
It might also be fine to see your kernel configuration file.
Have you made sure world and kernel are in sync, 3rd party kld's
are build?
To get the kernel dump, please use swapspace at least as large as
your machine has memory (RAM) installed and set dumpdev properly.
A dmesg also does not hurt to see how your machine is equipped.
