There is also a complaint for pine64 from Emmanuel Vadot: https://lists.freebsd.org/pipermail/svn-src-head/2017-December/106954.html reporting that as of -r326347 : The board just hang when plugin usb device That would seem to match my rpi2 reports: I have a USB SSD on a powered hub for the root file system on the rpi2 that I was using. (Recently the mmcsd0 mechanism to hold in the sdcard is broken but the eject mechanism still works. I hold in the sdcard during the early boot. But I've used a USB SSD for such small boards for a long time.) --=20 You are receiving this mail because: You are the assignee for the bug.=
