[Bug 1518457] Re: kswapd0 100% CPU usage
I had this issue too on AWS. In my case, it was the udev rule for vm-hotadd and the fix as mentioned previously basically came down to "touch /etc/udev/rules.d/40-vm- hotadd.rules" which effectively disables the /lib/udev/rules.d/40-vm- hotadd.rules file (after a reboot). The udev rule basically seems to only be active for Xen or Hyper-V and while it seems the Hyper-V stuff was also present in previous versions, the Xen stuff seems to be introduced in 15.10 or newer. So if you're seeing this issue on anything running on Xen, including AWS, try: touch /etc/udev/rules.d/40-vm-hotadd.rules reboot This is probably a bug in Xen or a bug in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1518457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well, they're probably waiting for the patch to hit the LTS kernel 4.4 branch, which will probably happen on the 18th May... Or something like that. But you can easily run it until then... Use the 16.04 Beta 2 AMIs, but just disable kernel updates (say, with "apt-mark hold") and update everything else. That will basically give you all the final stuff, just without the last few kernel updates, including the one that broke most EC2 instances. When a working kernel gets here, just apt-mark unhold and you should be good.

Its based on original patch series by Tony Luck and Kanaka Juvva. Memory bandwidth monitoring (MBM) provides OS/VMM a way to monitor bandwidth from one level of cache to another. The current patches support L3 external bandwidth monitoring. It supports both 'local bandwidth' and 'total bandwidth' monitoring for the socket. Local bandwidth measures the amount of data sent through the memory controller on the socket and total b/w measures the total system bandwidth. Extending the cache quality of service monitoring (CQM) we add two more events to the perf infrastructure: intel_cqm_llc/local_bytes - bytes sent through local socket memory controller intel_cqm_llc/total_bytes - total L3 external bytes sent The tasks are associated with a Resouce Monitoring ID (RMID) just like in CQM and OS uses a MSR write to indicate the RMID of the task during scheduling.

Currently also encountering this issue (the same kernel panic) with ami- 3079f543 on eu-west-1 with a c3.large instance. So this seems to be a general ubuntu 16.04 on AWS issue and not an upgrade specific issue. I haven't seen this issue with the beta2 AMIs. Interestingly I seem to be able to start the AMI on t2.micro instances, so this could well be instance type specific. ** Attachment added: "AWS Kernel panic log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573231/+attachment/4648152/+files/aws.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573231 Title: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do- release-upgrade -d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
