Dmesg repeating the same lines constantly

When I try dmesg all I get is the following lines repeated constantly.

X:3431 conflicting memory types e0d2e000-e0e2f000 uncached-minus<->write-combining
reserve_memtype failed 0xe0d2e000-0xe0e2f000, track write-combining, req write-combining

I recently installed a SSD for my system files, could this be the cause and is it something I should worry about?
Anyone know what it's trying to tell me?

Seems to be X+mtrr+PAT related.

Add nopat to your kernel boot options or remove PAT feature from the kernel.

PAT is designed as an improved memory/caching control along the lines of mtrr, but it seems the code to operate it is not mature yet. So for now just turn it off, and eventually it will probably be working (and a better choice).
