Comment 19 for bug 1930754

Hi Yuan-Chen

I tried:

"echo on | sudo tee /sys/bus/pci/devices/0000\:00\:16.0/power/control"

I also tried unloading mei* kernel modules.

However it didn't solve the isssue.

Here is the requested info:

# lspci -vvnns 00:1f.6

I also compiled the latest version of e1000e in https://sourceforge.net/projects/e1000/

root@latitude-5420:~# modinfo e1000e | grep ver

vermagic: 5.10.0-1038-oem SMP mod_unload modversions

But it didn't help.

I am currently using the wireless adapter until a find a solution. Sadly, the only solution provided by technical support was to re-install Ubuntu, which I will do when I find free time.

Many thanks,
Sebastian
