The module exists, but nothing loads it by default.
in rc.local or wherever you have it set up to use deadline, you also need
to modprobe deadline-iosched.
I never had to do that before. I just noticed there error message today,
but looking back it seems to have first shown up on February 10th.
I am using the scheduler=deadline kernel parameter in grub.conf.
If I do it that way, do I add something to /etc/modprobe.conf?
