Public bug reported: == Comment: #0 - Akshay Adiga - 2016-09-22 23:55:06 == ---Problem Description--- boot arguments (passed as CONFIG_CMDLINE) are not being picked up by kernel while using gcc-ppc64-linux-gnu v5.4.0 and v6.1.1. (gcc v5.3.1 works fine) ---Steps to Reproduce--- enable following config options in .config CONFIG_CMDLINE_BOOL=y CONFIG_CMDLINE="<required boot args for the system>" CONFIG_CMDLINE_FORCE=y
build kernel image and kexec without additional boot args. The system does not boot as it does not get the boot args. I have debugged to issue to gcc compiler optimization : https://lists.ozlabs.org/pipermail/linuxppc-dev/2016-September/149026.html The problem has been reported and fixed in upstream gcc https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71709 Need to backport this fix for gcc-ppc64-linux-gnu v5.4.0 onwards. ** Affects: gcc-defaults (Ubuntu) Importance: Undecided Assignee: Taco Screen team (taco-screen-team) Status: New ** Tags: architecture-ppc64le bugnameltc-146668 severity-high targetmilestone-inin--- ** Tags added: architecture-ppc64le bugnameltc-146668 severity-high targetmilestone-inin--- ** Changed in: ubuntu Assignee: (unassigned) => Taco Screen team (taco-screen-team) ** Package changed: ubuntu => gcc-defaults (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1628207 Title: boot arguments passed in CONFIG_CMDLINE not being picked up by kernel with gcc-ppc64-linux-gnu v5.4.0 and v6.1.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1628207/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
