Francois, ping? Is there anyone else that has access to this kind of
information about these chips?
It's kind of interesting that there's only been one report of this
though. Either the affected chips are rare among people testing
2.6.34-rc or there's something more to this. Maybe something
wierd/unusual about JÃrn's system?
JÃrn, are any other devices on your system working with 64-bit
addressing? Try doing this:
find /sys -name "*dma_mask_bits*" | xargs cat
Does anything show more than 32?
I've slightly changed the command:
# for i in `find /sys -name "*dma_mask_bits*"`; do echo -n "$i: "; cat $i; done

One device, which should be this one:
