I'm wondering if this is a microcode bug, since I have one of the new Skylake CPUs (Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz; stepping: 3; microcode: 0x6a) and others have mentioned crashes in __lll_unlock_elision related to broken CPUs/BIOSes, though for older generations.
For anyone who wants to see what the problems around elision lock is all about, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=800574 (libc6: lock elision hazard on Intel Broadwell and Skylake).
