Kernel log

With Leap 42.2 I have the root partition in btrfs for the first time, and I
encounter a soft lockup (log attached).  It looks like this could be a
duplicate of #999550, I am not 100% sure though - I do not see any correlation
to laptop sleep / resume.  In fact this typically occurs when I'm doing day to
day compilation, at random - roughly once a week.

I guess I need to bisect to find the issue, but I don't have a known good point
to start from... so I'm not sure where to start.
