On some of my production boxes, I'm running a 4.4 kernel on a 4.0 userland :) You should be able to build a 4.4 kernel, copy it to /kernel.test, and do a quick reboot to see if it works. That way you can fall back to the 4.2 kernel if you have problems. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
