Public bug reported: 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

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 no

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

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. On Sun, Feb 24, 2019 at 2:12 AM Gene Olson wrote: > I got a good example of a v5.0-rc7 kernel exception attached. I can't > reproduce them easily, althoug

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.
