Gene, this bug appears to be a duplicate of one you filed on 1/30/2019. I will duplicate this one over to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813999

Gene, upon further investigation, I made a mistake suggesting this bug is a duplicate of your earlier bug. We will investigate this bug stand-alone.

Not a duplicate. The previous bug was a problem with the display which
first appeared in linux -44, which was duplicated and confirmed fixed in
-45. This is a new problem caused by excessive Ethernet traffic. This is
a different problem that existed in -43 and still remains in -45. It
should not be marked as a duplicate.

These two bugs manifest on the same hardware, but they are different bugs.

This bug looks like similar to previous bugs such as bug 1729674, bug 1785780 and bug 1792574.

Gene, can you try running `sudo ethtool --offload <network_interface> rx off` and see if you can reproduce the issue? If so, could you attach the output from 'lsusb -v'? Perhaps we can build a kernel for you to test.

I tried what you suggested. Ethtool reported no changes in configuration
when I turned off receive offload. It reported substantial changes when I
turned off transmit offload. After turning off transmit offload, transmit
rate dropped from 930 Mb/s to abut 660 Mb/s, although I did not see a big
CPU hit. Receive speeds were not affected by turning off receive offload.

gene-pc:~$ sudo ethtool --offload eth0 rx off

gene-pc:~$ sudo ethtool --offload eth0 tx off
Actual changes:
tx-checksumming: off
tx-checksum-ipv4: off
tx-checksum-ipv6: off
tcp-segmentation-offload: off
tx-tcp-segmentation: off [requested on]
tx-tcp6-segmentation: off [requested on]
gene-pc:~$

Unfortunately, after doing this, I have had great difficulty reproducing
the crash, and I do not know why. Here's what changed: I did a routine apt
update, but I did not get a new kernel. I installed ethtool, and did the
command you suggested. After doing that, the system refused to crash
either transmit or receive. So I rebooted, this time did not run ethtool,
and the system again refused to crash. Previously I could reproduce the
crash in about 30 seconds. Now I cannot reproduce the crash after over an
hour. An hour of transmit, and an hour of receive. And an hour
bidirectional. I do not know why.

One problem here is that I test at home and at work, with the same
computer, but with a different TB-10 dock, monitor, keyboard, mouse.
Previous to my bug report, I had never seen the problem at home. The bug
report I sent was from work. Since receiving your request for information,
I cannot readily reproduce the problem either at home or at work. Except
once. I did see a crash at home when *I unplugged/plugged in a keyboard
while the test was going on*. I have attached three lsusb outputs:

   - usb.work →At work, system healthy.
   - usb.home → At home, system healthy.
   - usb.failed → At home, after the crash where I moved the keyboard

What else can I do to help diagnose the problem?

bidirectional.  I do not know why.

One problem here is that I test at home and at work, with the same
computer, but with a different TB-10 dock, monitor, keyboard, mouse.
Previous to my bug report, I had never seen the problem at home.  The bug
report I sent was from work.  Since receiving your request for information,
I cannot readily reproduce the problem either at home or at work. Except
once.  I did see a crash at home when *I unplugged/plugged in a keyboard
while the test was going on*.  I have attached three lsusb outputs:

- usb.work →At work, system healthy.
   - usb.home → At home, system healthy.
   - usb.failed → At home, after the crash where I moved the keyboard

What else can I do to help diagnose the problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v5.0-rc7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".

Thanks in advance.

I ran the 5.0.0 kernel, sending data bidirectionally with iperf3. It
failed after about 10 minutes, I lost the Ethernet and the keyboard/mouse
connected through the TB-10 dock. Unfortunately I forgot to do an lsusb -v
in the crashed state.

After rebooting, I ran iperf3 again, bidirectionally for an hour. No
hiccups, no errors. Talking to two other machines (one transmit/one
receive) the XP 15 maintained 933 Mb/s bidirectional with no dropped
packets for the entire time. Previously total bidirectional bandwidth was
limited to about 1.3 Gb/s, with a bandwidth varying both transmit and
receive.

How else can I help?

So seems like v5.0-rc7 doesn't have this issue?

It did fail on the first run after about 10 minutes. It did not fail again

Ok, please attach dmesg when this issue happens, preferably under v5.0-rc7.

The dmesg in comment #1 didn't record useful information.

I got a good example of a v5.0-rc7 kernel exception attached. I can't
reproduce them easily, although I could when I first filed my bug report.
Now it takes a few hours of full bore Ethernet traffic. This crash I once
again lost many/most of my usb devices.

It's helpful to know that after I lost the USB devices in the kernel
exception, I moved the KVM to a builtin USB port.

The TB16's ASMedia xHC (USB controller) dies:
[89535.271614] xhci_hcd 0000:0a:00.0: xHCI host not responding to stop endpoint command.
[89535.271945] xhci_hcd 0000:0a:00.0: xHCI host controller not responding, assume dead

I'll escalate this issue to Dell.

Great! Thank you!

Be warned that Dell might blow you off. Last I looked, they do not
officially support Linux on the XP 15. However they do support Linux on
some other systems that use the TB-10, including the very popular XP 13. I
would *guess* those systems will reproduce the same problem.
