Public bug reported: Occasionally (about once every three weeks) my machine experiences a kernel panic somewhere in the ext4 code on shutdown (and only on shutdown).
Ubuntu Version: 18.04, x86-64 Platform: AMD Ryzen R7 2700 on an Asrock AB350M-Pro4 mainboard. I attached two photos of the panic messages, one occurring on May 16th, the other on June 26th. The call trace is identical in both. Given how similar the messages are, I don't think this is an intermittent machine-related glitch. As of yet, however, I could not identify a pattern on when the issue occurs. Kernel versions: - May 16th: 4.15.0-20-generic - June 26th: 4.15.0-23-generic ** Affects: ubuntu Importance: Undecided Status: New ** Tags: kernel-bug ** Attachment added: "panic-may-16.jpg" https://bugs.launchpad.net/bugs/1779063/+attachment/5157297/+files/panic-may-16.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779063 Title: Occasional kernel panic on shutdown in ext4 code (dquot_drop) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1779063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
