I saw a bunch of similar errors on 3.14.x up to and including 3.14.4, running Java (Tomcat) and Postgres on Xen PV. Have not seen it since "mm: use paravirt friendly ops for NUMA hinting ptes" landed in 3.14.5. 402e194dfc5b38d99f9c65b86e2666b29adebf8c in stable, 29c7787075c92ca8af353acd5301481e6f37082f upstream As I did not follow the original discussion I have no idea if this is the same thing, and I'm way too lazy to look for it now. ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
