I had some hickups (X11 hanging) with -rt7. that did not [yet] occur
under -rt8. The changelog contains a note about fixing an
hrtimer deadlock. I'm not sure if that's correlated, but it looks like it.

On debian based distro's - instead of doing a `make bzImage` just call
 `make-kpkg kernel_image` and you'll find a *deb in the parent folder
afterwards. My work-flow looks like this:

#manually untar/patch & configure
VERSION=2.6.29.1-rt8
cd /usr/src/linux-$VERSION/
CONCURRENCY_LEVEL=4 nice make-kpkg kernel_image
dpkg -i ../linux-image-${VERSION}*Custom*.deb
m-a -l $VERSION a-i sl-modem tp-smapi kqemu
update-initramfs -k $VERSION -c
update-grub
reboot

That makes it fairly easy to keep track and cleanly remove old kernels,
since they're .deb packages.
