 |
|
Hi, after more than a decade of absence i am coming back to gentoo.
i just downloaded
| Quote: | | livegui-amd64-20250413T165021Z.iso |
but have no connection to the internet with my
Ethernet Realtek [10ec:8125]
dmesg tells me:
| Quote: | | r8169 0000:07:00.0 error -ENODEV: unknown chip XID 688, contact r8169 maintainers |
so i tired to unload and load the module:
| Code: |
modprobe -r r8169
modprobe r8169
|
according to this link r8169 should be the right driver
https://bpa.st/6SPA#1L8-L8
| Code: | lspci -knn
Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller [10ec:8125] (rev 05)
Subsystem: Gigabyte Technology Co., Ltd Device [1458:e000]
Kernel driver in use: r8169
|
now i have tried to manually copy the source from github via usb to my livesystem but i can't compile the new driver:
https://github.com/notpeelz/r8125
| Quote: |
make
make -C src/ clean
make[1]: Entering directory '/run/media/gentoo/RESCUE1200/r8125-master/src'
make -C /lib/modules/6.12.21-gentoo-dist/build M=/run/media/gentoo/RESCUE1200/r8125-master/src clean
make[2]: Entering directory '/run/media/gentoo/RESCUE1200/r8125-master/src'
make[2]: *** /lib/modules/6.12.21-gentoo-dist/build: No such file or directory. Stop.
make[2]: Leaving directory '/run/media/gentoo/RESCUE1200/r8125-master/src'
make[1]: *** [Makefile:205: clean] Error 2
make[1]: Leaving directory '/run/media/gentoo/RESCUE1200/r8125-master/src'
make: *** [Makefile:48: clean] Error 2

thanks for your tips
kind regards
SOLUTION:
install with a live cd that has the driver and using dist-kernel >6.13 (I used 6.14)

My new PC has the same issue with the r8169 kernel module.
The Gentoo livegui iso image starts with no wired Ethernet, so I can not go ahead and install Gentoo.
Does somebody know where to download a live iso image with a >=6.13 kernel and supporting the RTL8125 2.5GbE Controller?
However I solved the issue of not having a Ethernet connection by
- using a cheap and tiny USB-to-WLAN adapter.
- an other solution is using a USB-C connected smart phone, enabling Developer Options and then enable RNDIS (USB-Ethernet)
- plug in a PCIe x1 Ethernet card into the PCIe x16 Motherboard slot
I installed Gentoo with a 6.14.4 kernel from gentoo-sources.
The RTL8125 controller works, but badly. It disconnects and reconnects all the time when stressed.
It uses the r8169 driver from the kernel source.
It also requires firmware from linux-firmware see | Code: | | dmesg | grep firmware |
At the moment I'm using and other Ethernet card until setup with KDE works.
Then I will check why it works badly. |
