Description John Levon 2012-03-05 07:10:20 EST
Running up to date FC16 x86-64, choosing the 3.2.7 kernel fails to mount root due to "invalid raid superblock" on the root partitions. Obviously it's tricky to capture the details, but I can take a photo if it's helpful.

3.2.6 and earlier work fine.

Does the 3.2.9 kernel update (pending stable push) in F16 work for you?

Sorry, I don't know how to install that version.

You should be able to grab it with 'yum update' now, it has been moved to stable and mirrored out.
Comment 4 John Levon 2012-03-07 18:52:49 EST
I can confirm this kernel version fixed the issue again - thank you.
