------- Comment From ru...@us.ibm.com 2017-02-16 19:28 EDT------- >From the recently dup'ed bug: This looks to be just a new informational warning added to the 4.9 kernel: commit 63f53dea0c9866e93802d50a230c460a024c44e5 Author: Michal Hocko <mho...@suse.com> Date: Fri Oct 7 17:01:58 2016 -0700 mm: warn about allocations which stall for too long Currently we do warn only about allocation failures but small allocations are basically nofail and they might loop in the page allocator for a long time. Especially when the reclaim cannot make any progress - e.g. GFP_NOFS cannot invoke the oom killer and rely on a different context to make a forward progress in case there is a lot memory used by filesystems. Give us at least a clue when something like this happens and warn about allocations which take more than 10s. Print the basic allocation context information along with the cumulative time spent in the allocation as well as the allocation stack. Repeat the warning after every 10 seconds so that we know that the problem is permanent rather than ephemeral. I suspect this is nothing more than the high memory stress tests triggering a new warning. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1664708 Title: LTPstress :- genload: page allocation stalls on Ubuntu 17.04 , Power NV system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
