We are, though thanks for the suggestion. We've also fiddled with 
various BIOS settings, including IOMMU. I was hoping that someone had 
seen something similar with pagecache corruption. I've done a lot of 
searching on bugzilla.redhat.com. If it were a straight memory timing 
problem, it would seem to me we would see more random crashes and not 
this weird 4k-page corruption, which seems like issues with page tables 
or something like that.
