I encountered some (relatively) minor issues with USB3 connectivity on my main x86_64 system (flash drives not always being recognised on connection), so have reverted to 3.10.11 for the time being..
Unlike recent kernel versions, which have been EOL (End Of Life) after the next major version was released, the 3.10.x series is due to be supported ‘long term’… So – expect to see 3.10.12 etc. in due course..
