At first the PCTV worked OK, but now I've been getting a page allocation

Further testing on this shows that even if I free up lots of memory with

It will still fail if it has already failed and not been replugged.
It's not failing to allocate - it's just not trying to allocate AFAICT ,
which I guess counts as a bug?
