--- xenial ---
debian/rules needs --enable-arm to enable arm events. I have a test build of the rasdaemon package in ppa:centriq-team/lp1741978-rasdaemon. I tested this on an ARM64 system and confirmed with QTI that the output is as expected. The patches tracked in this bug are already fix-committed for xenial.
