Find out why linux kernel module was loaded

The debian backports 4.8 standard kernel loads the module fjes on my thinkpad T460s.

How can I find out why this module is loaded, i.e. which hardware triggers loading this module?

Actually you can run # lsmod to check all modules loaded. And you can check fjes module info with # modinfo fjes.ko.If I am not mistaken.Another users also post the question about fjes module.It called Fujitsu device.

You can use lspci -v. You will need to grep (probably with -i to ignore case) for your module shown in lsmod. e.g. to find r8169:

lspci -v |grep -i -A 4 -B 4 r8169

You can change the number of lines before and after (A, B) to your liking/needs.

I found another user had the same question. There is a script here to find out.

Check with lspci -v by itself. Question: is fjes showing up in lsmod? I think fjes is a Fujitsu Extended Network Device Driver. Did you check your ethernets/wifis/networks in the lspci output?

lspci only shows Intel devices and a Realtek one (SD card reader).

– Jan
Jan 5 '17 at 21:54

That's... pretty odd. Got on my debian machine, lspci shows everything. Are you doing this as root/elevated privileges? I will admit, I am not on a laptop, and do not have your kernel installed (I bet). I think the script on the link I posted could be modified to search all directories in /sys/class and print them. That may or may not help your cause.

My bet is that the module is loaded but not needed at all...
