I try to remember to reboot every couple weeks or so even without a
kernel update.  There sometimes updates to things like the "rc" stuff
or udev or whatnot which occasionally cause boot-time problems.  If
you let too much time go by between reboots, and something that
happend several months ago is going to cause a problem at boot time,
that reboot is guaranteed to happen when it's the most inconvenient.
And it's a lot easier to figure out the problem when it's due to a
recent update.
