Hi Sebastian, Sorry to hear it's not working on your side. That means the current direction currently been working on does not really solve the issue happens in your combination.
Here is what you can try: 1. upload sosreport log. like run `sudo sosreport`, and upload the output file in /tmp. 2. Try to find ways to work around the issue. - does the set rx-usecs 6000 work around it? - Let me assume you are using OEM image. With it, tlp and certain config files to make power consumption better are installed. Per my previous test, the other way to workaround is $ sudo ethtool --set-eee _enp0XXX_ eee off $ sudo tlp ac -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.10 in Ubuntu. https://bugs.launchpad.net/bugs/1930754 Title: e1000e extremly slow Status in OEM Priority Project: Confirmed Status in linux-oem-5.10 package in Ubuntu: Confirmed Bug description: We have dell latitude 5420 & 5520 laptops with onboard intel ethernet controller. Problem is that the ethernet port is extremely slow. about 100kbyte/s download throughput while on a gigabit connection. Upload seems to work just fine. Also when I pxe boot the system it's also painfully slow. But here comes the funny part. When I attach a usb memory stick the throughput of the networkcontroller is as expected. I've used latest ubuntu 20.04.2 kernel 5.8.0-55 I've used latest ubuntu 20.04.2 kernel 5.10.0-1029-oem Turns out this problem is not showing up when I manually install the 5.8.18 kernel. Also when I create my own iso with the help of Cubic and install the 5.8.18 kernel in it the pxe boot is working as expected with high throughput system: Dell latitude 5420 + 5520 nic: Ethernet Connection (13) I219-LM ubuntu 20.04.2 module: e1000e Please assist.
