"Even if the kernel runs fine, keep your eye on dmesg for OOPSes -- these
are definitely bugs regardless of whether they cause you problems."
If you are regularly testing development kernels, it is really useful to save the dmesg(1) output from every kernel that you boot. I added this to my /etc/rc.local
dmesg -s 100000 > /dmesg/$TSTAMP-$REL
Then when I notice something odd happening I can check whether anything new and interesting showed up in the boot messages.
I've spotted a lot of issues by simply running diff(1) on the current and previous dmesg output.
