I bisected a bug than manifests itself on 32-bit i386 architectures to commit 4f9007359bcd28bc83c63cb9af38d8b2c8c1670d for long term kernel 3.16.61. It appears as one of two cases, varying by cpu architecture.
All of them fail with an error message variation of "systemd[1]: Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' ". The difference is whether it freezes systemd or causes a kernel panic. I do not see this problem with the upstream kernel, so 3.16 probably needs a missing upstream patch. Below are two representative failure messages. # AMD K5 [ 3.063769] systemd[1]: Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at ../systemd-238/src/basic/time-util.c:69, function now().
