So instead of downgrading my BIOS, I've updated it from 1.2.29 to
version 1.3.0 which was released two days ago by DELL for the XPS15
9550. USB ports at the TB16 is now working without issues again.
I don't get any checksum errors, too:
for i in 1 2 3 4; do curl -s
Thank @Mario for this clarification, I recently updated my BIOS, too.
Since then under Linux my mouse and keyboard (connected to the USB ports
of the TB16) stop working from time to time. In Windows Mouse and
Keyboard are just sometimes laggy but don't stop completely. I will try
to downgrade the
@Daniel Aden: The fix was release in Kernel 4.4.0-93.116, please update

You posted that you are using 4.4.0-92-generic #115.

Hi Kai-Heng,
I can confirm your Kernel is working on my XPS 15 9550 + TB16 running
Zesty and it fixes the Ethernet issue.
But, the whole TB16 USB3 Controller including Keyboard, Ethernet and
other USB devices are still not working when connected during system
start. I need to disconnect and
Ohh okay, thanks for this advise I will order an adapter and try it out.
This seems to verify that the problem exists somewhere in the usb3
controller/driver (ASM1042A) in the TB16 and not in the Ethernet
controller/driver itself.

I need to correct me: Having issues during high load on the USB3
Ethernet adapter, too.
Only workaround is limiting to 100MBit.

@sforshee: You would suggest an other solution, e.g. setting the default

Since I upgraded to Ubuntu 17.04 (fresh install), I can confirm that
this bug also affects the (now) current release and therefore kernel
version 4.10.0-19-generic.
I also now implemented an other "workaround" and bought an 7€ USB3->1Gb
Ethernet dongle, this works without issues.

Is it possible that this bug could also affects zesty (linux-

For me it feels like this, randomly my system (Dell XPS15 9550, Samsung
NVMe PM951 512GB) hangs and I am unable to execute commands. Even dmesg
is not callable :/ ... I can reproduce this bug most of the times
reloading the Realtek kernel module r8152 and restarting the network-manager
also fixes the problem temporary:
sudo rmmod r8152.ko
sudo modprobe r8152.ko

Workaround:
Limiting the connection speed to 100MBit FDX via "ethtool eth. speed 100
duplex full autoneg on" also circumvents the problem.
On Windows 10 its working without issues at full speed (Gigabit).
