Comment 3 for bug 149997

Oh, by the way, here's how I'm reproducing this bug, starting from scratch:

1. Plug the computer into a wired network connection.
2. Install Gutsy Tribe 5.
3. Reboot into the newly installed system.
4. Run Update Manager.
5. Click "Check."
6. Perform a "partial upgrade" when prompted.
7. Once the partial upgrade finishes, reboot.
8. The new kernel fails to boot all the way.

I haven't tried installing Gutsy beta then applying updates (yet). If that reproduces it, that would be quicker. However, I *know* the above procedure reproduces it for me.
