Thanks for the information.  I'll try and switch back to the older
Where are new kernels announced?  How do you monitor or know that if you
do a yum upgrade that it will upgrade to a new kernel.

	I'm assuming you didn't remove your older kernel or kernel
modules.  The easiest way to go back is to edit /boot/grub/grub.conf and
change the default= parameter to your older kernel.  0 is the first
kernel listed in grub.conf , 1 is the 2nd, etc.  So if your grub.conf
looks like the following:
	title Fedora Core (2.6.14-1.1644_FC4)
	        root (hd0,0)
	        kernel /vmlinuz-2.6.14-1.1644_FC4 ro root=LABEL=/ rhgb
	        initrd /initrd-2.6.14-1.1644_FC4.img
	title Fedora Core (2.6.14-1.1637_FC4)
	        root (hd0,0)
	        kernel /vmlinuz-2.6.14-1.1637_FC4 ro root=LABEL=/ rhgb
	        initrd /initrd-2.6.14-1.1637_FC4.img
	Then kernel 1637 will boot by default.
	You should be very careful about updating to new kernels.  I try
to wait 3-4 weeks after a new kernel is released before upgrading so
ATRPMs can catch up and release new kernel modules for the latest
kernel.  Also, new kernels also mean new trouble.  There have been
infamous kernel version that destroyed ide drives and or damaged CPU.
The latest is not really the greatest in Linux, the almost latest is the
greatest ;).

mythtv onto FC4.  I set everything up a couple of week ago and all was
fine but I think FC4 has bumped the kernel version and I can't seem to
get the kernel modules.  I'm not new to Unix but I am new to Linux so
I'm a little lost.  

		        I installed the OS and did the: yum upgrade  (so
far so good).  It upgraded the system and installed the
2.6.14-1.1644-FC4 kernel.  Not I'm list because Axel doesn't seem to
have the kernel modules for lirc, nvidia, ivtv (I need the development
ones as I have a PVR-150) yet. 

		        Should I wait or go back to an older kernel?
How to I go back to an older kernel?  I don't mind reinstalling from
scratch as this is a new box that I'm setting up but if I do then how to
I specify what kernel to upgrade things to.
