Title:
  kernel crash when compiling linux-4.1-rc2 with make -j20

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Kernel crash whilst building new kernel:

  Steps to reproduce:

  wget https://www.kernel.org/pub/linux/kernel/v4.x/testing/linux-4.1-rc2.tar.xz
  tar xf linux-4.1-rc2.tar.xz
  cd linux-4.1-rc2/
  make mrproper
  make olddefconfig
  make -j20

  I noticed that the output from the build had stopped then noticed the
  following messages (via dmesg):
