Alright, thanks. And I'm guessing you don't currently have a problem
*without* either of the fixing patches, because your device tree
doesn't use rng-seed. Is that right?

In anycase, I sent in a revert to get all the static branch stuff out
of stable -- https://lore.kernel.org/stable/20220607084005.666059-1-Jason@zx2c4.com/
-- so the "urgency" of this should decrease and we can fix this as
normal during the 5.19 cycle. But with that said, I do want to get
this fixed as soon as possible still. I'll be back at my desk tonight
and will finally have access to real hardware again. Are you hitting
this by loading a 32bit kernel on a raspi4? Or running a 32bit kernel
on the raspi1? Or some other combo?
