This is definitely a kernel bug, but it's exaggerated by userspace. So whether it should be worked around in userspace or fixed in the kernel space is debatable.
For now, I believe you can employ that workaround to keep your system stable, but I would ask the following. 1) Can you please follow the things that the bot said to add your logs to the bug. 2) Can you please try latest mainline (5.1rc7: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1-rc7/) and confirm it doesn't help? I don't expect it to. 3) If the fwupd workaround does end up being backported to Disco, please test it for the purposes of the SRU, you would see notification in this bug. ** Changed in: fwupd (Ubuntu) Status: New => Triaged ** Also affects: linux (Ubuntu Disco) Importance: Undecided Status: New ** Also affects: fwupd (Ubuntu Disco) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Eoan) Importance: Undecided Status: Incomplete ** Also affects: fwupd (Ubuntu Eoan) Importance: Undecided Status: Triaged ** Changed in: fwupd (Ubuntu Disco) Status: New => Triaged ** Changed in: linux (Ubuntu Disco) Status: New => Incomplete ** Changed in: linux (Ubuntu Eoan) Importance: Undecided => High ** Changed in: linux (Ubuntu Disco) Importance: Undecided => High ** Changed in: fwupd (Ubuntu Eoan) Importance: Undecided => Low ** Changed in: fwupd (Ubuntu Disco) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826691 Title: fwupd hangs after 19.04 upgrade from 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupd/+bug/1826691/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
