Bingo. The problem doesn't seem to happen using linux-image-4.14.0-3-marvell_4.14.17-1 from sid. I've now successfully transferred 1.5TB from an external USB drive onto the internal hard disk. Previously the problem would show up within the first few 100MB of the transfer. Do you want me to help figure out which change to the kernel fixed the problem? - Menno
