Maybe related,

I got a
Nov  9 23:59:33 rpi2b-1 cc[39999]: stack overflow detected; terminated
Nov  9 23:59:39 rpi2b-1 kernel: pid 39999 (cc), jid 0, uid 0: exited on signal 6 (core dumped)

trying to build a nodebug (16:main) kernel from n281766 with 
-j4 on armv7 (rpi2b+) but using src and obj and ccache dirs 
mounted on fast nfs

Trying again wiht -j2.
