The messages I got were not the cause problem. The panic I was able to get shows this: http://pastebin.com/dHnB3Xh0 I can't get any further with core although I compiled virtualbox-ose-kmod with debug symbols (I used make config to enable them, because I think -DWITH_DEBUG does not work because kmk is used in the build process). Any help will be appreciated. Gus
