Module not loading on latest Linux Mint/Ubuntu kernel 6.5

Hello,

Looks like something changed by this commit recently,

• https://lore.kernel.org/lkml/[email protected]/T/#maf36ff06626a1477f652908e77dc15387ffc335b

And it seems this also makes the developers something more on their module but I am not sure.

I will investigate and patch our project 🤔

Late update, but recently I updated my server to kernel 6.5 it just works... after some fixing.

$ uname -a
Linux awesometic-nas 6.5.0-14-generic #14~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Nov 20 18:15:30 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Right after the kernel update and reboot, the module wasn't loaded and I found that the vermagic is not updated to the new kernel version.

I thought that is not compiled in the kernel updating scripts, and I gave a shot to reinstall this package using apt.

$ modinfo r8125 | grep vermagic
vermagic:       6.5.0-14-generic SMP preempt mod_unload modversions

And reboot again, and it works again.

Just a note for the other people, I don't think I had the same problem with you because I couldn't see any message on dmesg when the ethernet didn't work.

Hello awesometic, I am also having this problem with your latest release, module no longer loads "Right after the kernel update and reboot, " Ubuntu server 22.04. So I reinstalled module using sudo dpkg -i, however the module no longer loads after a new kernel is installed. Can you please advise how to fix? Should I reinstall using apt? Many thanks!!

[awesometic]

Hello @barkmann44, in my case I can fix it by reinstalling the Debian package.

sudo apt install ./realtek-r8125-dkms_9.012.04-1_amd64.deb --reinstall

Is vermagic correct to your new kernel? If so, is there any message in dmesg?

[awesometic]

Seems like kernel 6.5 breaks so many DKMS friends :)

Dear awsometic, thanks for responding!

Prior to running apt install, I get this:

vermagic: 5.15.0-92-generic SMP mod_unload modversions

Then trying to install via apt:

I see there is a permission denied message for apt. Does this look right to you? Thankyou in advance!

Okay, I get it now. Maybe it is another problem with the Debian package. 🤔

Let me have some time to look into this problem. :)

[awesometic]

Lastly, could you send me the results of this command?

sudo dmesg | grep -i r8125

And,

sudo insmod /lib/modules/$(uname -r)/updates/dkms/r8125.ko
sudo dmesg | grep -i r8125
