The reason I vote know is that ENOEXEC can mean several things. I thought you had a patch to catch the actual kernel error message and pass it back to userland. That would be a useful feature, but this message doesn't really help and can point people in the wrong direction if their error is due to a different problem. If you want to help the user, then I think a more useful approach would be to tell the user to check dmesg for error messages when kldload(2) fails with ENOEXEC. -- John Baldwin
