Absent much USB3 WRITE activity being involved because rsync is not finding differences to copy over, this seems to be far more rare. That includes the "spurious link down" messages being rare and there likely being no READ error messages. For example: 2 "spurious link down" notices and 1 "WRITE(10)" message sequence. The pattern can happen with just a USB3 boot drive and the other USB3 port not in use. Again significant USB3 write activity increases the frequency greatly. For the retries remaining notices, I've only seen "3", never more or less. I see this with upstream pkgbase distributions of main booted (debug or non-debug kernel and debug boot world) --and with my personal kernel builds (same boot world). The rsync status display activity for a transfer between the two USB3 drives hangs up for temporary periods around when there is this sort of messaging going on. -- === Mark Millard marklmi at yahoo.com
