Thanks!  This problem should go all the way to when MSI support was 
introduced (2.6.28):

a80dc3e0e0dc ("AMD IOMMU: add MSI interrupt support")

But I don't think that's a correct fixes tag because
irq_managed wasn't introduced until 3.19:

cffe0a2b5a34 ("x86, irq: Keep balance of IOAPIC pin reference count")

But then I tried to go off the original introduction of the error 
message, but that's quite ancient.

1da177e4c3f4 ("Linux-2.6.12-rc2")

So which tag do you think is appropriate to use?  I'm tempted to say 
this should just be without a fixes tag just a:
