There are lots of spinlock issues fixed with a kernel that is in our
testing repo ...



You can get it like this:

place the testing repo file in /etc/yum.repos.d/ ... the repo file is


Then you can get the testing kernel (or kernel-smp, kernel-hugemem. etc)
with the command:

yum --enable-repo=c4-testing install kernel

(or kernel-smp, kernel-hugemem, etc.)

(did I mention this was a testing kernel ... :)
