tar xzf linux-6.14.9.tar.gz

Ah that explains the difference. You didn’t just rebuild the kernel you jump to the next version. The FOG developers typically only use long term supported kernel. Currently the latest long term kernel is 6.12.x, you used a development kernel 6.14.x which is not EOL (just means fixes and updates will not happen in this branch).

It looks like whatever was causing the slowness was resolved in 6,14.x and later versions of the linux kernel. Thank you for the clarification.

You are welcome to continue using the “OEM driver” kernel for now until I create a full upstream release.

What did you do here, did you fold in the realtek oem driver into the kernel build. I was looking at going this path for another open issue with a realtek 8125, where the oem driver solves a lot of the issues with the default universal drive 8169.

[rodluz]

@george1421 That is exactly what I did, I disabled the 8169 driver from the kernel config too.
I think I know what other issue you are talking about. The release that I posted earlier only has the 8168 driver.

I just uploaded a kernel with 8125, 8126, and 8168 drivers, if you want to try it out for that issue.

Good going. That 8125 driver was originally in the linux kernel individually but then the driver was merged into the 8169 unified driver which has not kept up with the realtek hardware changes. I was getting lost trying to integrate a third party driver into the linux kernel. I could compile it as a module and add it to the init.xz but that is not a sustainable solution. If you have it integrated into the kernel for the 8169 (1GbE) and 8125 (2.5GbE) that should cover most of the common network adapters today from realtek (outside of the 10GbE stuff, but those haven’t hit the desktops yet).
Well done!

@george1421 @rodluz
Out of curiosity, when will this hit the production FOS image? Be handy to not need to purchase Dell Ethernet Adapters.

[rodluz]

@Clebboii @olivier-bonnici I created an experimental kernel that includes the drivers to fix this issue. Would you be willing to test it and let us know how it goes?

[Clebboii]

@rodluz Absolutely, where can I find it?

[rodluz]

@Clebboii I just noticed an error in how FOG displays the experimental kernel/init releases. For now, please get it from here: https://github.com/FOGProject/fos/releases/tag/EXP_20250630

[Clebboii]

Hi @rodluz,

Apologies for the late reply to this. Could you please provide me with the init.xz and bzImage for this experimental kernal?

[rodluz]

@Clebboii It is now a general release (not in experimental phase). You can update to the latest kernel and init from the FOG settings pages or using this link: https://github.com/FOGProject/fos/releases/tag/20250715
