No idea why page > allocator would think your UMA "local node" has no memory though. but ... as i said it in my report, this is a regression since v2.6.24 - v2.6.24 (and a whole bunch of commits since then, i listed the IDs) booted up fine. The commit ID you mention is: v2.6.23-4345-g523b945, way earlier than the good commit IDs. so this is a recent regression. Ingo | ||||||||||||
