It's not necessary to overwrite your current kernel. You can do something like this, which is what I do to test kernels. cd /usr/src;make -s installkernel KODIR=/boot/test;cd nextboot -k test reboot This does a one-time start using the test kernel under /boot/test. Your other option is to describe the problem and ask if anyone using 8-current has encountered it. --- Gary Jennejohn
