It could by another driver. I tried with a different filesystem (xfs), without any I/O scheduler and even with the sources on a different drive without dm-crypt, and the results were more or less the same - lockups involving dm-crypt. Maybe I'm just abusing the system - I'm actually running "make -j", so the number of tasks is unlimited. With a limited number it does not hang. I know it's not a good idea to do this but it used to work, and I think it shouldn't cause the kernel to die like this.
