Well, I'm trying to get a test together - although I don't have webdav anywhere... I was going to try it via FTP, however I'm hitting another MM bug in Xen: https://bugs.archlinux.org/task/38596 This references: https://lkml.org/lkml/2014/1/23/596 It says that should be fixed in 3.15-rc3 (if I understand properly) - but I'm also hitting that on 3.14.2. Did these changes get ported back to the 3.14 tree?This is fixed by 29c7787075 (mm: use paravirt friendly ops for NUMA hinting ptes) which is tagged for stable but hasn't yet been picked up for 3.14.y. You can also work around it by disabling CONFIG_NUMA_BALANCING which doesn't work with Xen PV guests anyway.
Hi David, Just wondering if there has been any movement in getting this into 3.14.y. I see we've now just hit 3.14.4 with no mention of the patch for issue. -- Steven Haigh Email: netwiz@crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299
