--- Comment #91 from Nils Beyer <nbe@renzel.net> ---
(In reply to Don Lewis from comment #89)

really interessting research you've done there; big thanks for that. If the
shifting of the shared page really helps getting the system stable, is it s=
till
a hardware problem/bug then or more a software problem? If hardware, is that
fixable by a microcode update or is the CPU design per-se "incompatible"? W=
hat
do you think?

Anyways, I've applied your patch and started a poudriere build. Based on yo=
ur
experiences, I'm somewhat optimistic now. I'll let you know how's it going
here.

The "ryzen_segv_test" still fails despite the patch, the only way to circum=
vent
that is to disable SMT. But that's no final option for me...
