see the hang anymore using 5.4 on 20.04.
Thanks for following up.

So I have reason to believe this is fixed in kernel 5.2 and later by
this commit:
https://github.com/torvalds/linux/commit/8ae5b1d78d4acbe9755570f26703962877f9108a
Would someone affected be able to check the with a modern kernel if it
can still reproduce? On some Renoir hardware I found that as f
eoan has reached end of life, so this bug will not be fixed for that

I'm marking eoan as fixed, as it has 1.2.10 which contains the
workaround to avoid using synaptics mst on amdgpu devices.
The kernel tasks is still open as this is still a real kernel problem.

So this issue needs to be reported upstream to AMD @FDO.

Having the very simple replicator should be good to include it too.

Sorry, our messages must have crossed paths.
Appears to be the third device from the strace of the fwupd process in
the hung state.
$ grep -i drm strace.log | tail -n 2

You're probably right about the driver. I've seen other complaints from
the drm layer around amdgpu. I'll try to watch dmesg more often to catch
more of these.
Just added the files from apport.

This is a small C program doing exactly the same thing as fwupd does to
trigger this issue. Usage: `sudo ./read-dpcd /dev/drm_dp_aux`.
To find out what is, replace ExecStart property in
`/lib/systemd/system/fwupd.service` from `/usr/lib/fwupd/fwupd` to
`/usr/bin/strace -D -tt -y -f -o /var/lib/fw

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.

Thank you very much. I think I can live with the first option. I'll look
more into the implications, but it seems to be better than not having
the process running at all.
Not sure if I need to do anything to close this.

This is a bug in the amdgpu kernel module.
When trying to access the DP aux channel it is causing system hangs.
At least in upstream fwupd there is a recently committed workaround:
