The commit "powerpc/imc: Dont create debugfs files for cpu-less nodes" - 41ba17f20ea835c489e77bd54e2da73184e22060 is already in focal (since Ubuntu-5.4.0-8.11).
The commit "powerpc/powernv: Avoid re-registration of imc debugfs directory" - 48e626a got upstream accepted with 5.5, hence it not yet in focal. I'm going request to add it to focals 5.4. -- 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/1861379 Title: [Ubu 20.04][kernel-5.4.0-12-generic] debugfs: Directory 'imc' with parent 'powerpc' already present! lot of messages logged while booting Status in The Ubuntu-power-systems project: Triaged Status in linux package in Ubuntu: New Bug description: == Comment: #0 - Kalpana Shetty <[email protected]> - 2020-01-29 22:46:37 == ---Problem Description--- [Ubu 20.04][kernel-5.4.0-12-generic] debugfs: Directory 'imc' with parent 'powerpc' already present! lot of messages logged while booting ---uname output--- root@ltc-wcwsp3:~# uname -a Linux ltc-wcwsp3 5.4.0-12-generic #15-Ubuntu SMP Tue Jan 21 17:56:24 UTC 2020 ppc64le ppc64le ppc64le GNU/Linux Machine Type = Witherspoon DD2.3 Test Environment: Hardware: Witherspoon-DD2.3 Ubuntu 20.04 kernel: 5.4.0-12-generic #15-Ubuntu Steps: 1.
