Ok, thanks for checking up on this.

Sure, but the question still remains: do you want to panic on
uncorrectable errors by default or want the user to decide? I guess this
is something you can answer for your hardware...

Off the top of my head, I'd first look at compiler asm output to
check what my compiler does with those writes and then take a look at
employing the ACCESS_ONCE macro or something similar where we use the
asm volatile() as an optimization stop for the compiler, among others.
And then I'll look at asm again to make sure it does what it is supposed
to do. Something to that effect, in any case...
HTH.
