> David, can you look at this bug (email answers to this email are fine)?

I've been looking on and off at this bug and haven't forgotten it.

I've checked the obvious things like whether the PCI front-end supports
full 32-bit addresses (all documentation states that it does) or whether
there is some signedness issue with how the driver handles DMA
addresses (I cannot find any such problems).

I'll reply again if I make any more progress on this bug.

I do have a QFE card somewhere and an x86 system with 4GB of ram
so I might try to reproduce this problem locally in the end.
