Why not boot the old kernel and try it out? Same for other components.

FC4 won't auto remove previous kernels, though the update sites only keep
a few revisions back (i.e. I don't see any 2.6.14 FC4 kernel rpms), so if
it really was a 2.6.14 kernel and you already removed them you might have

But check your /var/cache/yum, if you haven't been cleaning it out, all
the old kernels (and rpms) will still be there.


	find /var/cache/yum -name 'kernel-2*'

And install (rpm -ivh) one of the older kernels etc.

You could still install and run the original FC4 kernel, even though
intermediate updates are not available. I could not install it via yum,
but you could download:




Of course you don't want to have that old of a kernel running with the box
on the internet.

You could also build your own kernel via kernel.org source, see if a
2.6.14 works OK or not, and then bisect from there, I haven't ever tried
git bisect. If an earlier kernel *does* work, you'd probably have to do
some sort of bisect to isolate the change, and report to FC devel.
