Interesting. I need to have a poke at that - it used to work fine but
I've not tested the 821x recently and the HPA code has changed. It
shouldn't be issuing HPA commands in the first place. Added to the TODO
list. The HPA is supposed to be cleared by the driver setup code but if
the newer firmware is faking it then I wonder what it does if we allow
the command through.
