Is everything fine there? At least it's identical between 4.0.5 and 4.1.6: image=/boot/kernel-genkernel-x86_64-4.0.5 label=Linux405 read-only # read-only for checking root=/dev/ram0 append="init=/linuxrc keymap=de ramdisk=8192 real_root=/dev/sda6 splash=verbose,theme:default console=tty1 quiet radeon.modeset=1 video=radeon:mtrr:3,ywrap,1680x1050-32@60 ahci.marvell_enable=0" initrd=/boot/initramfs-genkernel-x86_64-4.0.5 Don't ask me where all those options came from, they grew with time... > Here are my RCU kernel config options.

The only difference to my config there is that I have CONFIG_RCU_FANOUT=64 and CONFIG_RCU_CPU_STALL_TIMEOUT=60 (don't ask me where the values come from, I don't remember ever setting them different from the default). But since that is all the same between 4.0.5 and 4.1.6, I don't think it has anything to do with my problem. Could the RCU message just be telling me that since the machine doesn't properly boot, it doesn't have anything to do? Cheers, Peter.
