Sorry for the top-posting!

But as I see these RCU (CPU) stalls, the patch from [1] might be worth a try.
First, I have seen negative effects on my UP-system was when playing
with linux-next [2].
It was not clear what the origin was and the the side-effects were
somehow "bizarre".
The issue could be easily reproduced by tar-ing the kernel build-dir
to an external USB-hdd.
The issue kept RCU and TIP folks really busy.
Before stepping 4 weeks in the dark, give it a try and let me know in
case of success.

For the systemd/cgroups part of the discussion (yes, I followed this
thread in parallel):
The patch from [4] might be interesting (untested here).

Hope this helps you.
Have fun!
