Just happened two days ago on Trusty 14.04.4 with Linux 4.4.0-31 on one of Ceph Jewel OSD server. It ran fine for 8 days though and suddenly the CPU load spiked to 600. The server is from SuperMicro SuperStorage Server SSG-6048R-E1CR36L with these following specs: 2x Intel Xeon E5-2630 v3 @ 2.4GHz 16C/32T 128GB DDR3 ECC 2x 80GB Intel SSD S3500 series for OS Drive in mdraid1 mode 2x 800GB Intel PCIe SSD S3700 series for Ceph OSD Journal 36x 6TB Samsung NAS 7200rpm SAS drives for Ceph OSDs 4x 10GbE SFP+ Intel 82599ES ethernet with LACP bonding mode The apport-collect log is attached.

I have been running the -29 kernel from http://people.canonical.com/~smb/lp1568729/ for about two weeks now, so far without triggering the bug. With the kernel from Tim, the bug could still be triggered. So it seems there were different patches. I'll try the -33 kernel from ppa as well, to see if there is any difference. -- 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/1568729 Title: divide error: [#1] SMP in task_numa_migrate - handle_mm_fault Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: While running qemu 2.5 on a trusty host running 4.4.0-15.31~14.04.1 the host system has crashed (load > 200) 3 times in the last 3 days.

[Kernel-packages] [Bug 1568729] Re: divide error: 0000 [#1] SMP in task_numa_migrate - handle_mm_fault
The whole discussion seems to be going back and forth and is rather confusing. On one side there is the ceph discussion where Stefan Priebe indeed mentions that he has many more patches in his tree. On the other side there is the LKML discussion which ends in GregKH getting exactly one patch submitted for 4.4 and 4.6 (https://lkml.org/lkml/2016/7/12/297). This is the backport of the last of the 3 patches in comment #11. I am not sure whether Peter Zijlstra just as well got confused in the end or it turned out that in older kernels one only needed the last one. From the references in the patches, the last one refers to the second and the second refers to the first. Practically the last one works around certain values becoming 0 in certain corner cases. Which causes the divide errors. So maybe it is enough. As for the last test kernel done by Tim: although is answer when I asked about what was in there sounded like it might be the same set, I am starting to doubt that from the time-line. That kernel was done in April and all three patches I had were 4.7-rc1 or later which looks to be from May. So I cannot really believe that those were in discussion back then. So what I would like to propose: I created a PPA and uploaded a kernel with just the last patch applied (https://launchpad.net/~smb/+archive/ubuntu/xenial/+packages). This is the state that is queued upstream for 4.4.x longterm (but not yet released). Someone who can see the issue should actually test this kernel. Regardless of any reports on the ceph list. Because if this does not fix the problem this should be discussed upstream. -- 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/1568729 Title: divide error: [#1] SMP in task_numa_migrate - handle_mm_fault Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: While running qemu 2.5 on a trusty host running 4.4.0-15.31~14.04.1 the host system has crashed (load > 200) 3 times in the last 3 days.

There is one person on the Ceph mailing list who thinks this is fixed in 4.7rc6 (http://thread.gmane.org/gmane.comp.file- systems.ceph.user/30793/focus=30987). Unfortunately, I haven't been able to figure out a precise patch set that can be applied to 4.4 to fix it. -- 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/1568729 Title: divide error: [#1] SMP in task_numa_migrate - handle_mm_fault Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: While running qemu 2.5 on a trusty host running 4.4.0-15.31~14.04.1 the host system has crashed (load > 200) 3 times in the last 3 days.
