Hi, Thank you for your responses. I used the information from this script to get a clean Debian environment: https://www.raspberrypi.org/forums/viewtopic.php?t=104981&p=745746 https://github.com/ShorTie8/my_pi_os my_pi_os.sh
My /etc/fstab: #<file system> <dir> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/mmcblk0p1 /boot/firmware vfat noauto,noatime 0 2 /dev/mmcblk0p2 /boot ext2 defaults,noatime 0 0 /dev/mmcblk0p3 / f2fs defaults,noatime 0 0 /dev/sda1 /evsj f2fs defaults,noatime 0 0 My /etc/apt/sources.list: deb http://ftp.fi.debian.org/debian sid main contrib non-free deb-src http://ftp.fi.debian.org/debian sid main contrib non-free Kernel 4.14: Test1: console=tty0 console=${serial} root=/dev/mmcblk0p3 rootfstype=f2fs rw elevator=deadline fsck.repair=yes net.ifnames=0 rootwait Test2: dwc_otg.lpm_enable=0 console=tty0 root=/dev/mmcblk0p3 rootfstype=f2fs elevator=deadline rootwait Test3: rpi2 and rpi3 Test4: .dtb from 4.14 and 4.13.
