I've upgraded my laptop to F8 using "yum upgrade". This has left me with the new kernel-2.6.23.1-42.fc8 as well as my previous kernel-2.6.22.9-91.fc7. The 2.6.23 kernel won't boot on this system. It gets as far as the initrd lines and then it just hangs. Luckily the 2.6.22 kernel still works (with some caveats that I'll mention in a different mail) so I can still work. But it would be great to get the new kernel working too. Cheers, Dave...
