My custom has been to build world and kernel, install world and kernel,
then reboot promptly. Not sure where I got the  habit from, the idea 
was to minimize mismatch between kernel and userland.

If I did this right, no luck...

Perhaps it's time to install the new kernel and reboot.

I also have two kernels that report uname -p as armv6, one pre-hf and one post-hf. Worth a try?

Thanks for all your help!
