Right now I just do a reboot loop, systemd creates cgroups during boot
this dump took 84 reboots. Harder to reproduce with more trace_printks.
CONFIG_SCHED_AUTOGROUP looks interesting though, might try that next week.
Appears that the call comes from idle_balance or rebalance_domains,
since they are the only ones that call load_balance.
New more detailed trace:
