Yes, I did.

I can now confirm that 284034 is the culprit. Unfortunately, that single
commit MFCed 10 updates of which 6 may be the problem. I tend to suspect
the PCI changes rather than the CardBus patch, but I will spend a little
time looking at the individual commits in HEAD to see which, if any, touch
both PCI and CBB.

Adrian, I don't have the ability to test on head ATM, so, if you have a
chance, go for it. Most if this is way beyond my ken, so I am extremely
unlikely to spot it.

I am adding jhb@ to the CC as 284034 was his commit.
