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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1826691 Title: fwupd hangs after 19.04 upgrade from 18.10 Status in fwupd package in Ubuntu: Triaged Status in linux package in Ubuntu: Incomplete Status in fwupd source package in Disco: Triaged Status in linux source package in Disco: Incomplete Status in fwupd source package in Eoan: Triaged Status in linux source package in Eoan: Incomplete Bug description: 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu $ lsb_release -rd Description: Ubuntu 19.04 Release: 19.04 Being a firmware updater, the machine is probably relevant - Dell 7730. 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center $ apt policy fwupd fwupd: Installed: (none) Candidate: 1.2.5-1ubuntu1 Version table: 1.2.5-1ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu disco/main amd64 Packages 100 /var/lib/dpkg/status 3) What you expected to happen I expected few/no issues after 19.04 upgrade. The fwupd process worked perfectly in 18.10. It's upgraded the firmware on my laptop twice since I installed 18.10. 4) What happened instead After upgrading from 18.10 to 19.04 I had an issues that when I tried to suspend my laptop using the same button press as previous, the laptop would be hot and screen flickering when I returned to reopen it. I thought there were power management issues in the upgrade, but I've traced it to fwupd not letting the PM suspend process complete (see dmesg below). I tried shutting down the fwupd daemon with systemctl but the command hangs forever. All of the fwupdmgr commands timeout. Thinking something might have broken in the upgrade, I tried uninstalling (purge) the fwupd package and reinstalling. Starting the process with systemctl hangs forever like stopping it. Trying to kill -9 the process does not work - in uninterruptible sleep (D). This crash is probably related. It happened a couple of ours before I tried to put it to sleep the last time before uninstalling fwupd.
