unable to boot upgrade setup

[HeikoAdams]

Hi,
today I've tried to upgrade my f16 machine to f17 but without success. Booting the setup fails because dracut claims a missing or empty "root=" parameter followed by a kernel panic.

Booting into a previous F16 kernel and updating to a newer F17 kernel would probably be the most painless way of fixing it. You could try enabling the updates repo if one isn't available yet.

Looks suspiciously like a usrmove problem. The original poster doesn't say how he did the "upgrade" if he did a yum upgrade, or preupgrade.

No and no!

This is https://bugzilla.redhat.com/show_bug.cgi?id=785815 . And for the specific preupgrade instance of the bug, it's https://bugzilla.redhat.com/show_bug.cgi?id=800205 .

Oops, I just saw "kernel" and "no root" and thought it was a common mkinitrd bug.

Lots of last minute changes for the release this time! At least there will be lots of new features.
