So far, i've not been able to reproduce this. I have 6282 based QNAP NAS box, with a single disk. Since this is a kernel hacking box, i tftpboot and don't use an initrd. I've been using the mvebu_v5_defconfig kernel configuration and i have tried v4.13-rc2, v4.12, v4.10.0 and v3.9.30. And i have sid for user space. Andrew
