Kernel panic due to ALX driver

[Niko Z.]

Hello,

I just installed Kubuntu 19.04 on MSIGP60 and enjoy using it but seem to have a kernel issue. I realize that this is not Kubuntu specific, but it is the only Linux system that I have installed at this time, so I was hoping someone more knowledgeable than me could help with the issue.

My CPU rises to 100% quickly after logging in. After some investigation with KSystemLog I saw the culprit in the form of endlessly repeating messages:

                         kernel    [ 2804.187465] alx 0000:04:00.0 enp4s0: fatal interrupt 0x4001607, resetting

This seems to be a known issue with some ethernet drivers.

What I have tried so far:

1. Temporary attempted fix has bricked my session:

sudo rmmod alx

2. I also ran the following with no appreciable result:

 sudo ifconfig enp4s0 mtu 9000

I am out of my depth here. Does anyone know how to deal with this driver? I don't need wired connection.

Much obliged,

Niko Z.

Run

inxi -Fxx

and post the results in a CODE box. The "F" is upper case and the "xx" is lower case.

If you don't have inxi, do this:

sudo apt install inxi

, the run the above.

I edited

/etc/modprobe.d/blacklist.conf

by appending

blacklist alx 
blacklist mdio

That seems to have done the trick.
