Soren, if you post a patch for 4.x I will be happy to follow-up
with Brady. I've been working with Brady for several days now trying
to track down corruption in the vm_page array. I *really* want to know
if a VIA chipset patch solves his problem, because it would
also explain about a dozen similar bug reports over the last 6 months.
(Which would also be good backing to get it into 4.5).
