eSATA
One user reported getting this error with an eSATA device in a docking station. It seems to have been related to a bespoke AHCI driver used in/by a recently-installed storage manager (in that particular case, Intel Matrix Storage Manager software, but others may exhibit the same behavior). Once that software was uninstalled, the problem was resolved. This information is provided on an 'as is' basis, without prejudice, as we have not tested nor replicated here.
