Matt, I think it's fine that upstream has demoted the BUG_ON, as I haven't heard anyone report this with a kernel later than 3.13; I assume whatever is causing it is fixed in later kernels.
At this point there's not much more I can do, as I can't reproduce it and don't have much debug info on exactly what/why the zone's pfn range becomes incorrect. If you or anyone has any info on how to reproduce this, or you have a system where it's reproducable, please let me know. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1497428 Title: kernel BUG at /build/buildd/linux-3.13.0/mm/page_alloc.c:968 Status in linux package in Ubuntu: In Progress Status in linux source package in Trusty: In Progress Bug description: The kernel triggers a BUG when it finds it is in move_freepages() but the start and end pfns for the move are in different zones.
