After yum update, kernel-3.3.8-1.fc16.i686 was brought in.
When I rebooted this morning into the new kernel, kernel
panic'ed because it was unable to mount root by it's uuid.
I had opened a bug at
bugzilla.redhat.com against
kernel-3.3.5-2.fc16.i686, which panic'ed in the same way,
but that bug has been deleted (or so it seems, because searching
for it yields no hits. I had also filed the bug
with
bugzilla.kernel.org (big mistake!!!) and it also has
been deleted. That bug id was 822792.
Before these bugs were deleted, there were replies that
problem was in dracut.
But no solution was provided.
