Steps to Reproduce

1. clone wrlinux testing layer

git clone git://ala-git/projects/wassp-repos/testcases/wrlinux wrlinux-testing -b WRLINUX_7_0_HEAD

2. configure and build altera-socfpga project with standard kernel

configure --enable-board=fsl-ls10xx --enable-kernel=standard --enable-rootfs=glibc_std --enable-test --enable-jobs=8 --enable-parallel-pkgbuilds=8 --with-layer=<path to wrlinux-testing>/wr-testing/ltp,<path to wrlinux-testing>/wr-testing/kts --with-template=feature/kts-standard

3. boot the target arriaV (barcode 21954)
