Do you still see crashes in systemd within pthread code or is it
something else? The update should have disabled lock elision
completely, so if it SIGILLs on haswell, it ought to SIGILL on
everything, which it doesn't.
Either way, an early microcode update is indeed the best way out, so
if that works, we could just drop the glibc update. But it would be
great to know what's actually going wrong so that if it's something in
glibc even with elision disabled, we can get that fixed.
