--- Comment #12 from Alexey Dyachenko <adotfive@gmail.com> ---

i5-5675C is affected as well (with GA-Z97-HD3 rev2.0 F9; Arch Linux). I have
disabled Turbo Boost, as BIOS doesn't have setting for SpeedStep, C1E,C3,C6/C7
were also disabled, however the issue still occurs.

"processor.max_cstate=0 intel_idle.max_cstate=0 idle=poll" does not help.

Speaking of instructions these CPUs are indeed affected by HLE bug

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6b877e0 in __lll_unlock_elision () from /usr/lib/libpthread.so.0

Thinking its some instruction that causes MCE, I recompiled glibc without
elision lock and with -march=ivybridge and installed linux-ck-ivybridge,
however machine still hangs under load (like compiling glibc).
