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. Thank you
