Recently I haven't been running f16 kernels on rawhide because of a
recent dependency change in f16 to require a higher version of a package
than is in rawhide. The rawhide package has the needed change so you
could do a nodeps install.

The debugging kernels since 3.1 seem to be worse than they were in the
past. For some people this was significantly impacting their display
performance, for myself, my I/O performance tanked. I use luks on top
of raid and I think the I/O is becoming CPU bound instead of disk bound
on my system.

My current solution is to rebuild kernels with most of the debug options
turned back off. I have a git branch with change to the debugging options
and when there is a new update I update my copy of the master branch,
megre master to my nodebug branch and then do a local build.
