I am getting lockups (always) after laptop opening from sleep. 

This behaviour is new at some point in the last few months  - in the same
hardware, in was not hapenning in Spring/early Summer Tumbleweeds. I did not
update this laptop for several months, this issue is new after update
early-September, and still an issue as of 2016-09-16.

The system locks up completely, but once I was able to get to the console and
there I see, repeatedly:

---------------------
NMI watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [btrfs-transacti: 761]
---------------------

System is AMD A8-6410 laptop, details below
