Hi Brian. I am on a _very_ tight schedule as is, since I have to go to Boston with a very packed schedule early Friday morning and I have a report and a homework for tomorrow plus I have to prepare a demo for Monday. However, Andreas and I have some 50 kernel boot instructions running using switched page tables before we get a crash, which is good news. We are now investigating excactly what causes the crash and next steps will be to handle this after having identified what goes wrong.
