hmm, further checking 4.4.52, it was not really OK too: [ 1895.084325] blk_update_request: I/O error, dev sda, sector 239461608 [ 1895.101099] sd 4:1:1:0: [sda] tag#1 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 1895.101101] sd 4:1:1:0: [sda] tag#1 Sense Key : Illegal Request [current] [ 1895.101103] sd 4:1:1:0: [sda] tag#1 Add.
