Subject: [4.4-rc2] regresstion: ksoftirqd/2 Fatal exception in interrupt pids.freepids.uncharge.constprop
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.

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,
