Hi all,
I have a amd64 computer with 4Go of memory. When i boot i have this error :
azalia0 at pci1 dev 0 function 1 vendor "ATI", unknown product 0xaa30 rev

0x00: can't map device i/o space

azalia1 at pci0 dev 27 function 0 "Intel 82801I HD Audio" rev 0x02: can't map

device i/o space
If i remove 2 Go of memory. These errors disappear. I Have try to disable

pci memory mapping in the bios. My computer have ~3,2 GB of ram but my

computer freeze randomly. Someone has an idea?
My dmesg :

The iommu is missing from your dmesg, so I guess the bios does not remap

the memory to give space for the pci configuration. This would result in

the symptoms described in the dmesg.
The output from the boot promt "machine memory" will show if I am right

with the above. If so, take a look into the bios options. There should be

a knob which should take care of the remapping. If there is no such knob

you should look for a bios update.
Kind regards,

   Markus

I have this problem only with amd64 version, the i386 version recognizes well 
Memory Map is enable in PCI Configuration setting.
Thanks,
