If you get input/output errors when running the above as root then check the dmesg log to see if there are any extra details (especially if you are running a self-compiled kernel).
If I do "echo 1 > /sys/devices/system/cpu/cpu4/online" I get input/output error.
Dmesg shows the same - just "input/output error" - nothing else.
I use Manjaro 5.5 kernel.
