OK. This is the same issue as the one on this thread here
http://www.ussg.iu.edu/hypermail/linux/kernel/0808.2/1532.html


We have too many entires in PAT list due to RAM pages being marked
UC by drivers. Unfortunately, there are no quick fixes that can fix
this for 2.6.27. However, we are aware of the problem here and
working on a more complete fix for this. We should have the patch
for it soon.

Thanks,
Venki
