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.

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.
