On the other hand, maybe the original MB86613 does not exhibit the issue.
The Pinnacle device is combined with another device or function, hence not
identical with MB86613:

BTW, I dimly remember hear-say about Fujitsu controllers, particularly
because they are among the few (or the only ones?) that featured a
programmable PhysicalUpperBound. So there was at least one Linux users who
had such a controller; perhaps as onboard controllers of a Fujitsu
notebook. (Which has got a shorter service life expectancy than a PCI
card...)
