I wrote: "PS: it's possible that that commit doesn't actually fix the underlying kernel crash, it just means that rr isn't triggering it any more, and that if you modified EFLAGS via the ptrace interface rather than r11 you'd get the crash back again." but looking at the kernel I think that is impossible, since the set_flags() function in arch/x86/kernel/ptrace.c sanitizes eflags if set via ptrace. The issue fixed by 29722cd4ef66 is that setting r11 in some situations would bypass the sanitizing.
