The interrupt latch bit should really not be set just by itself, as
its supposed to be an OR of the other interrupt bits. But, apparently
it can get itself into a state where only that bit is set, and
the interrupt signal is still on the bus. Your patch should work
for this case, because the docs say that the interrupt latch bit
can be explicitly cleared through acknowledgement.
