As the original impetus for this bug report: I cannot personally verify that this solves the original problem (https://answers.launchpad.net/launchpad/+question/285505) as it manifests itself on the Launchpad build farm and I do not have necessary hardware to reproduce this independently.
Latest attempt is https://launchpadlibrarian.net/242901620 /buildlog_ubuntu-precise- armhf.bladerf_2016.01-rc1+1SNAPSHOT20160225213708-git61c3b57~precise_BUILDING.txt.gz ... note presence of "Illegal instruction" within the log, and the kernel version of 4.2.0-30-generic on aarch64. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1545542 Title: Enable arm64 emulation of removed ARMv7 instructions Status in linux package in Ubuntu: Fix Released Status in linux source package in Wily: Fix Committed Status in linux source package in Xenial: Fix Released Bug description: Linux now supports emulation of three deprecated ARMv7 features that were removed from ARMv8: SWP(B), CP15ISB/DSB/DMB, and SETEND. At least CP15DMB is used by some armhf archive binaries (notably pandoc), so we need emulation enabled on the kernels that scalingstack uses. I haven't checked which version added which, but they appeared some time between 3.13 and 4.2, and I only care about 4.2 onwards. So please enable ARMV8_DEPRECATED, SWP_EMULATION, CP15_BARRIER_EMULATION and SETEND_EMULATION in arm64 kernels for wily onwards.
