In my lab i tried installing the  Unbreakable Kernel on a
ScientificLinux 5.5 x64 machine. The upgrade was a success
only after i removed the yum-priorities package.

The problem is that after the upgrade the system seems to be pretty
messed up.  During boot many errors are recorded about various
services. So even if the system seems to work, and the various errors
could be bypassed, it a bit risk to put something like this in
production...:-)

So, i suppose that installing the Unbreakable Kernel on SL5.5 its an
option, only if you feel very lucky!!!!

PS: Also i would like to add that, because my lab server  was a vmware
virtual machine, after the upgrade to oracle kernel , the vmware tools
stopped working. I tried
to reinstall them, but the compilation some of the vmware-tools modules
did not succeded...
