The latest kernel from yakkety-proposed does not appear to fix the problem. Note that I did test it on Xenial, not Yakkety, because I do not have an easy way to reproduce the bug that excercises rate-limited printk on Yakkety.
I made sure that the proposed kernel was used by comparing what is getting installed on Yakkety vs Xenial: On Yakkety ========== $ sudo apt-get install -y linux-image-generic/yakkety-proposed Selected version '4.8.0.44.56' (Ubuntu:16.10/yakkety-proposed [ppc64el]) for 'linux-image-generic' The following additional packages will be installed: crda iw libnl-3-200 libnl-genl-3-200 linux-firmware linux-image-4.8.0-44-generic linux-image-extra-4.8.0-44-generic wireless-regdb Suggested packages: fdutils linux-doc-4.8.0 | linux-source-4.8.0 linux-tools linux-headers-4.8.0-44-generic The following NEW packages will be installed: crda iw libnl-3-200 libnl-genl-3-200 linux-firmware linux-image-4.8.0-44-generic linux-image-extra-4.8.0-44-generic linux-image-generic wireless-regdb # uname -a Linux mmedvede2-test-ratelimit-pkvmci836 4.8.0-44-generic #47-Ubuntu SMP Wed Mar 22 14:27:02 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux On Xenial ========= $ sudo apt-get install -y linux-image-generic/yakkety-proposed Selected version '4.8.0.44.56' (Ubuntu:16.10/yakkety-proposed [ppc64el]) for 'linux-image-generic' The following additional packages will be installed: linux-image-4.8.0-44-generic linux-image-extra-4.8.0-44-generic Suggested packages: fdutils linux-doc-4.8.0 | linux-source-4.8.0 linux-tools linux-headers-4.8.0-44-generic The following NEW packages will be installed: linux-image-4.8.0-44-generic linux-image-extra-4.8.0-44-generic The following packages will be upgraded: linux-image-generic $ uname -a Linux mmedvede-test-ratelimit-pkvmci8361 4.8.0-44-generic #47-Ubuntu SMP Wed Mar 22 14:27:02 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux And I was able to reproduce the printk spam on Xenial with the proposed kernel. Did the fix actually get into 4.8.0.44.56? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667416 Title: PowerNV: No rate limit for kernel error "KVM can't copy data from" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1667416/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
