Hi Davidlohr, First bad commit (maybe != root cause): tree: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master head: f0939c364ffe7dc377c4d7946360f99cb7fc867b commit: 48803a970534ad0411991de1d293996db8ea9aa0 [10274/10671] ipc,sysv: return -EINVAL upon incorrect id/seqnum config: arm-arm67 (attached as .config) reproduce: wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross git checkout 48803a970534ad0411991de1d293996db8ea9aa0 # save the attached .config to linux build tree make.cross ARCH=arm Note: the next/master HEAD f0939c364ffe7dc377c4d7946360f99cb7fc867b builds fine.
