The same is observed on the X13s, so venus doesn't load.

Indeed, the older venus patches would simply force the system to hard reset in
EL1, and in EL2 there is a fault (but the system recovers without the hard
reset.)

I do have a further question, isn't the information we need somewhere inside a
TZ managed context bank? Can we even see in there from userspace? I really am
out of my league here, but I'm willing to do any testing needed on the hardware
and I can use b4 with the best of them ;)
