Almost all FC17 kernels are debug kernels. A quick way to tell if you're
using one is:

grep -i CONFIG_ACPI_DEBUG /boot/config-`uname -r`

'not set' = release kernel. 'Y' = debug kernel.

The kernel team is building one kernel per upstream kernel release (I
think that's it) as 'release' not 'debug', but you can quite easily
rebuild a kernel as 'release' instead of 'debug' yourself - just check
out the kernel package from git, do 'make release', then build it
however you like - e.g. 'fedpkg srpm' then 'fedpkg scratch-build'.
