I.e, isn't the firmware fix papering over a bug that should be fixed in
Linux mvpp2 driver anyway ?  

Absolutely. Leaving this unpatched in the kernel, with a 100% chance of
memory corruption is just mad.

I'm pretty sure there should be a way to sanely reset the interface
before it starts repainting the memory.

I agree here. Do you still have an image of that old firmware version,
so that we can try to reproduce, and see if we can come up with a way
to reset the BM on boot up that would avoid this issue ?

Yup. I still have both the original build tree as well as the sdcard, so
you should be able to trigger on demand.

I'll email you the stuff separately, unless you want another delivery
method.

Thanks,
