Dear Chris,

In message [ref] you wrote:

And what does fsck.ext4 -f -n get you?

No errors on any of the affected file systems.

Switching to Fedora 18 means many things have changed so it's
harder to find out, if software, what's causing it. Is it kernel
itself, is it md, is it the HBA driver?

Agreed. But as there are at least 2 different HBA brands involved it
appears we can exclude this part.

Best regards,

Wolfgang Denk
