I took both patches for a quick spin (a dozen boots and one hour uptime
after that for each patch) and no incidents. I have not gathered data,
but the crash on boot feels like it's quite a bit above 50% when there
is a problem so this feels good (I used 5 clean reboots when I bisected
and that worked).

(and please don't forget to cc stable)
I've decided to do a more in-depth fix, so that we also solve the issue
that when we schedule in these down_read()s, we don't leak the permissive
domain register setting into the switched-to context.

Can you test this patch please?  Thanks.
Still looking good.
Does that mean I can add your reported and tested-by to this latest
patch?

Thanks.
