According to your build log, RTM is disabled: RTM = CK_MD_RTM_DISABLE So I'm confused as to how TSX support in the build system's CPU could be the cause. I think your FTBFS might actually be due to #764827 ("ck: upper bound on cores being used in tests"). It looks like building on systems with a high number of cores can cause the test suite to take an unreasonable amount of time, so I've uploaded 0.5.2-2 which limits the number of cores used to a small value. Could you retry your build with ck >= 0.5.2-2 once it hits the archive? Thanks! -- Robert Edmonds edmo...@debian.org
