The new kernel has been released. Nothing to worry about now.

I guess this implies that you don't currently have a regular backup system
in
place?
When you say "load", you mean a giant 'cp'? That technically
works, but is not
the ideal. When you mount it in the new install, you'll find a bunch of
broken
uid/gids. Best is an archive format that preserves user and group names (say,
tar).
Tar up your existing OS (or the parts that you care about) leaving the tarball
on the external drive. After the reinstall, untar on the external drive.
Finally, work out a legit backup system in the new OS.
