As you can read in the comments, for me and others the problems went away after using a thicker more expensive SATA cable with firm braced connectors.
The logical conclusion would be that the same effect can be observed with two different causes (software and hardware) and I think it's important to acknowledge that. It might be easier to find out the cause (bug in newer kernels) when we know physical I/O problems trigger the same errors and messages.
