That's a good point. Also with total usable pfns = 2070237 and last usable pfn 2490368
there must be some PFNs in between that are IO-Devices mapped as you mentioned perhaps.
No I have not. I will try that and let you know what happens. cat /proc/meminfo actually gives MemTotal: 8280948 kB !!

Your complete system information to know will be good for better
understanding of your ptoblem. Means output of 'uname -a' and
processor/motherboard model.

I can't say exactly what is happening on your side, might be some
in-compatiblity of your motherboard (bios) with Linux Kernel. But the
thing which you can see is: point 8. Total usable pfns = 2070237 =
~8GB memory, so might possible your bios is telling IO-Devices mapped
region as some more memory available (but I am not sure about this).

Have you tried to read/write/kmap on pages whose pfns are giving
physical address after 8GB ? Is it working ? and what memory size 'cat
/proc/meminfo' is mentioning ?

Its better is you also do CC to kernelnewbies, so that some other
person might give you some better idea too. And please don't do
top-posting, rather do bottom-posting (search google for it) on
mailing-list while replying.
