Right ... that's why I was asking ... my 1030 works fine with MSI.  If
there's a fault with the FC boards, then certainly they should have MSI
disabled.

The motherboard was my suspicion ... especially as older ones have SPI
and newer ones have SAS (and the older ones are most likely to have MSI
faults).  However, I think you can see from our point of view that if
the problem is the motherboard, disabling MSI in the fusion is the wrong
way to fix it.  If we do it this way, we'll promptly get another slew of
nasty bug reports for the next driver that enables MSI and doesn't work
on this platform

Yes, we'll do that ... I'll also see if the PCI maintainer can determine
the information needed to blacklist the motherboards so that we don't
get this all over again with them and a different driver.
