Thanks for these details. The fact that the kernel copyright messages etc don't get displayed even with the old loader makes it seem unlikely that it is a direct problem with the module preloading. Maybe the kernel itself is corrupt - this could happen for example if the system did not shut down cleanly immediately after writing it to disk. Does the "lsmod" loader command display sensible results after "load /boot/kernel/kernel"? If ACPI causes problems, you can also check with lsmod that you haven't accidentally compiled it in. In theory it should be possible to load the kernel from the compile directory by giving the loader the full partition-relative path, e.g load disk0s1e:/obj/usr/src/sys/amd64/compile/MYCONF/kernel where "disk0s1e" is your /usr partition and the path is the compile directory relative to /usr. Unfortunately this doesn't seem to work for me, so it may not be much help. Ian
