Re: [Kernel-packages] [Bug 1815808] Re: Thunderbolt Ethernet high-traffic exception
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.

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.

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.

Re: [Kernel-packages] [Bug 1815808] Re: Thunderbolt Ethernet high-traffic exception
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?

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.

Re: [Kernel-packages] [Bug 1815808] Re: Thunderbolt Ethernet high-traffic exception
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?

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 rx off` and see if you can reproduce the issue? If so, could you attach the output from 'lsusb -v'?

Re: [Kernel-packages] [Bug 1815808] Re: Thunderbolt Ethernet high-traffic exception
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.

[Kernel-packages] [Bug 1815808] Re: Thunderbolt Ethernet high-traffic exception
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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1815808 Title: Thunderbolt Ethernet high-traffic exception Status in linux package in Ubuntu: Confirmed Bug description: Running iperf3 on Dell XP-15 with TB-10 Thunderbolt dock causes a kernel exception and ethernet failure after about 30 seconds. Easy to reproduce. Connect to another machine via Gig-E and run iperf3 in either direction until the problem occurs. Should run 900+ Mb in either direction. On one occasion I also lost the USB ports.
