Yes. The same patch will apply to 7-stable though it will have to be applied
to ata-chipset.c instead.
Here is that patch reworked, which I'm about to test shortly. I see the
fuzz confused patch(1).
... After manual fixup, I am now up and running with this modified
patch. Thanks John!
Not sure why it didn't work in 8.x, though.
cheers
