Hi, 1) on ppc64le lscpu works properly: ubuntu@fauck3:~$ lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 160 On-line CPU(s) list: 0-159 Thread(s) per core: 4 Core(s) per socket: 1 Socket(s): 40 NUMA node(s): 1 Model: IBM pSeries (emulated by qemu) L1d cache: 32K L1i cache: 32K NUMA node0 CPU(s): 0-159 ubuntu@fauck3:~$ ppc64_cpu --threads-per-core Threads per core: 4 ubuntu@fauck3:~$ dpkg-query -S /usr/sbin/ppc64_cpu powerpc-ibm-utils: /usr/sbin/ppc64_cpu ubuntu@fauck3:~$ ppc64_cpu --cores-present Number of cores present = 40 2) Do you agree that we need to handle this kind of error ? even though current proposed package is an updated package which works properly on ubuntu/trusty - so may be not necessary to go further. May be just handling a possible error and avoid a start fail.
