A manual loading of the module results in % kldload /boot/kernel/linux64.ko kldload: an error occurred while loading module /boot/kernel/linux64.ko. Please check dmesg(8) for more details. sleepdirt:fvwm:root[203] dmesg | tail -2 link_elf_obj: symbol elf64_linux_vdso_fixup undefined linker_load_file: /boot/kernel/linux64.ko - unsupported file type Now, that I look at /sys/amd64/conf/NOTES again, I find that there is a COMPAT_LINUX as well as the COMPAT_LINUX32. I must have conflated that two options into being the same thing. I have to update the system for the recent security announcement, so I update everything and change my kernel config file. -- Steve
