Public bug reported: The Bionic 4.15.0-1053 kernel package contains this nilfs2 bug: https://marc.info/?t=157413851100002
and it specifically concerns this nilfs2 commit for 5.3 which was apparently backported: https://marc.info/?l=linux-nilfs&m=157423529924889&w=2 My RPi 2B boots fine from nilfs2 on kernel 4.15.0-1052, but kernel -1053 oopses consistently and reproducibly, with exactly the same "nilfs_segctor_do_construct" pattern as in the above bug report. Reverting to -1052 results in a working, bootable system again. The -1053 changelog mentions: "Bionic update: upstream stable patchset 2019-11-21 (LP: #1853519)" which I suspect is the cause. ** Affects: linux-raspi2 (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/1860659 Title: 4.15.0-1053 contains fatal nilfs2 kernel bug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1860659/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
