How are you compiling your code? I used this makefile http://pastebin.com/f3ab71917 and all I typed was this: make sudo make install sudo make load and I get the hello, fail message, and then I typed sudo make unload and I got the unload fail message. Andrew Andrey was correct, param.h and kern.osreldate were not the same. thanks very much for the prompt responses. =jt ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

Check output of these commands: grep __FreeBSD_version /usr/src/sys/param.h sysctl kern.osreldate -- WBR, Andrey V.

That error is a sort of catch-all. But the kernel linker should put some more specific information out in the kernel console/dmseg. so 'dmesg' may help you if you have something like a bad symbol. respectfully, james toy ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
