Hi!

I saw this with 4.4-rc2 twice on boot:

pids.freepids.uncharge.constprop
cgroup_free

RIP pids.cancel.constprop.

I think somewhat after systemd mounted cgroup filesystems.

Had no digital camera at hand and I am on the go, so just these few pointers 
at the moment.

kernel config attached.

One change I made to kernel config that I enabled NUMA awareness. I think as 
this ThinkPad T520 only has a Intel Core i5 (not i7) it may not be able to 
make use of this.

Thanks,
