Public bug reported: When LANG is set to a non-English language with the relevant language pack installed, Kbuild's recordmcount.pl script fails to function correctly when building out-of-tree kernel modules on architectures that do not use the C version of recordmcount (e.g. ppc64le). This can result in invalid kernel modules being built.
This was due to the non-C version of recordmcount relying on parsing the output of objdump(1), which can be localized. This is now fixed in the linux-kbuild tree with the following commit: https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux- kbuild.git/commit/?h=kbuild&id=7b6954a982e7f60af38b835db52a06afc6e4b84c This commit is not in the torvalds/linux.git tree yet, but it would be good to backport the change to the Ubuntu kernel, particularly the linux-headers packages that are used for building out-of-tree kernel modules. Steps to Reproduce: 1. Set LANG to a language other than English (e.g. ja_JP.UTF-8) 2. Make sure that the correct language pack is installed and that localization is working; for example, run a command expected to print an error message, like `cp` with no additional arguments. 3. Install the NVIDIA GPU driver Actual results: The kernel panics when loading the nvidia-modeset kernel module. Expected results: The driver should install and load normally. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828084 Title: Kernel modules generated incorrectly when system is localized to a non-English language To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828084/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
