Do I have to do anything so that the server from now on always reboots using the old kernel-2.6.17-1.2174_FC5 ?
yes. in /boot/grub.conf: default=1 or a remove of the panic kernel. ('hope that the path is correct for xeon's)
How do I verify what kernel is in use now ?
uname -r
Is it possible to remove and prevent kernel-2.6.17-1.2187_FC5 or newer kernels from automatically installing during a yum update?
yes and yes. in /etc/yum.conf: exclude=kernel* *or* another trick: in /etc/sysconfig/kernel: UPDATEDEFAULT=no (not *the* answer to the question, but...)
Also, How would I go about troubleshooting the panic ?
