Sorry for the *really* late answer, but I did not have any time to do linux things the last weeks. :-(

Until my last mail from 7. Jan this was true, that I was not able to crash 2.6.24-rc6-mm1 with above patch. But after testing 2.6.24-rc7 with only the IOMMU changes applied it did crash once again. After looking at the patch that seems rather expected as it only touches powerpc code.

The resulting 2.6.24-rc7 kernel worked for me. I compiled 146 packages without a crash. Today I finally had some time for debugging again and tried the new 2.6.24-rc8-mm1. The crash is still there, I will report that crash in current thread.
