When I connect my Displaylink DL-165 adapter to my Debian/testing
machine, the "udl" driver is loaded and the following error messages
appears in kernel logs:

Hi,
A few more details. In the current configuration, inspite of kernel warnings the system is working, and I was able to configure both monitors (LCD in my laptop and external LCD monitor connected to
UDL-165).
I have followed the procedure described in https://wiki.archlinux.org/index.php/DisplayLink#USB_2.0_DL-1x5,_DL-1x0_Devices
# xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 1 name:modesetting
Provider 1: id: 0x17a cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
# xrandr --setprovideroutputsource 1 0
Afterwards I have configured screens in my Mate desktop using GUI.
However, the CPU occupancy is high and I get the following messages regarding the softmmu operation:

From time to time I also get the messages about the drm_get_object_put
Below are all the related messages. When I tried to disconnect the UDL-165 from USB socket, the whole system crashed immediately.

Hi,
A few more details. In the current configuration, inspite of kernel warnings the system is working, and I was able to configure both monitors (LCD in my laptop and external LCD monitor connected to
UDL-165).
I have followed the procedure described in https://wiki.archlinux.org/index.php/DisplayLink#USB_2.0_DL-1x5,_DL-1x0_Devices
# xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 1 name:modesetting
Provider 1: id: 0x17a cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
# xrandr --setprovideroutputsource 1 0
Afterwards I have configured screens in my Mate desktop using GUI.
However, the CPU occupancy is high and I get the following messages regarding the softmmu operation:

From time to time I also get the messages about the drm_get_object_put
Below are all the related messages. When I tried to disconnect the UDL-165 from USB socket, the whole system crashed immediately.

This is referring to
https://marc.info/?l=linux-fbdev&m\x154318725922207&w=2
I can reproduce this in Linux 4.20.0. Is there any additional info
that would help you fix this?
