Hello, > I can try this weekend whether removing systemd makes a difference. > Installing sysvinit-core made no difference. I tried the older backports-kernels and the problem exists already with linux-image-4.12.0-0.bpo.2-marvell_4.12.13-1~bpo9+1_armel.deb. (linux-image-4.11.0-0.bpo.1-marvell_4.11.6-1~bpo9+1_armel.deb crashed even earlier: [ 0.000000] INITRD: 0x00800000+0x00400000 overlaps in-use memory region - disabling initrd)
I found this bug report: https://www.spinics.net/lists/arm-kernel/msg653367.html ([PROBLEM] orion5x: Kernel boot panic at of_clk_get()/orion_mdio_probe() on a non DT box on linux-4.16.7).
