This test will take about 2 hours to run on node wright (ThunderX ARM64):
Test history:
4.4.0-155.182 - 1h45m
4.4.0-152.179 - 1h57m
4.4.0-150.176 - 2h00m
4.4.0-149.175 - 2h03m
4.4.0-147.173 - 1h55m
4.4.0-146.172 - 1h57m
4.4.0-145.171 - 1h59m

However it took about 25min to run on Moonshot ARM64 (node ms10-35-mcdivittB0-kernel),
Test history:
4.4.0-155.182 - 23m
4.4.0-152.179 - 24m
4.4.0-150.176 - 23m
4.4.0-149.175 - 23m
4.4.0-147.173 - 23m
4.4.0-146.172 - 23m
4.4.0-145.171 - 24m

Not sure why there is such a huge difference, but it might needs to be investigated.

Step to run the test:
  sudo apt-get install git python-minimal python-yaml gdb -y
  git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests
  git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
  rm -fr autotest/client/tests
  ln -sf ~/autotest-client-tests autotest/client/tests
  mkdir autotest/client/tests/ubuntu_btrfs_kernel_fixes/tmp
  mv autotest/client/tests/ubuntu_btrfs_kernel_fixes/fixes/* autotest/client/tests/ubuntu_btrfs_kernel_fixes/tmp
  mv autotest/client/tests/ubuntu_btrfs_kernel_fixes/tmp/361c093d7f99c3f6cbb07d5c580ce778ab418c42.sh autotest/client/tests/ubuntu_btrfs_kernel_fixes/fixes/
  AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_btrfs_kernel_fixes/control
