Can you try this rather than s2r:

for i in 1 2 3 4 5; do echo 0 > /sys/devices/system/cpu/cpu$i/online ; done
for i in 1 2 3 4 5; do echo 1 > /sys/devices/system/cpu/cpu$i/online ; done

and check the status if things are still corrupted for you?

I am working on a 5 cpu system grouped as 0-1 and 2-3-4.
Above doesn't corrupt anything for me Atleast.

And my system doesn't have S2R support for now.
