I had the exact same thing over here. Traced it down to the leftover "dos" filesystem add-on if you update an existing installation. If you remove "/boot/beos/system/add-ons/kernel/filesystems/dos" booting works as usual. But obviously it'd be nice if the crash could be avoided.

It's not really possible to avoid crashing in this situation. The FS and partitioning system module API changed and since we don't want to increment the interface version number with every change during development, the kernel has no way of knowing that a module is obsolete.

Should this be marked as Invalid ?
