The Read/Write failures started in 3.6.X kernels, but do not appear

3.7 is doing the right thing by first issuing a hard reset to the

drives before reading or committing the journals. 3.6.X was not
sending any
hard resets to the sleeping drives.
I will be testing 3.6.7 to see if either of these issues is still
present.
If it isn't, you can ask the Fedora kernel guys to batch port the fix.
If the fix is upstream, you can often get them to back port it.
FYI - for the fun of it.
