It actually seems to be hanging just after I've built my kernel and
do a:  find -name \*.c.smatch -exec cat \{\} \; > warns.txt

My screen froze but I was able to log in via ssh once and type dmesg
but then I hit tab tab twice to trigger the tab completion and it
hung for good.

I'm still not sure the big hang is related to the RCU stalls...
