I can confirm the same on a week old 4.99.64 kernel - only I could not
shut it down at all as my display was made unusable by an attempt to
run glxgears with DRI (that is another story). The machine continued
to serve NFS, but I could not ssh back in to claim my screen session
and see what has happened. The build.sh log was just half way through
with no errors to show.

This is on a dual i386 box.
