Hi All,
We still have some issues with PCI cards in our FSL P5020 and P5040
systems since the DMA mapping updates. [1, 2]
We have to limit the RAM to 3500MB for some problematic PCI cards.
(kernel boot argument 'mem=3500M')
The problematic DMA mapping code was added with the PowerPC
Great! I owe you a night worth of beers at a conference or if

Thanks for bisecting. I've spent some time going over the conversion
but can't really pinpoint it. I have three little patches that switch
parts of the code to the generic version. This is on top of the
last good commmit (977706f9755d2d697aa6f45b4f9f0e07516efeda).
Can you check with whіch one

What are the disks hanging off ?

We have the bad commit! :-) The PASEMI onboard ethernet doesn't work

Just as a warning: this series now has some conflicts with the dma
mapping tree due to the ->mapping_error removal, and there might be
some bigger ones if the direct calls for the direct mapping code series
goes ahead. None of them affect the early part of the series that do
not touch the actual

I completely missed your posting of V4 ! I was wondering what was
taking you so long :)
I'll give it a spin & send acks over the next 2 or 3 days.

The ones I sent pings for were either tested successfully by you
