Hi Alexander, |
| 2 |
|
| 3 |
A while back I had the exact same issue with a remote machine that I am |
| 4 |
managing. It has an Asus B45-M mobo with an r8169 chipset. Ever since |
| 5 |
the 5.2.x kernel family - where it last used to work - it has been a pain. |
| 6 |
|
| 7 |
Initially I added a manual "soft" dependency in "/etc/conf.d/modules" as |
| 8 |
William has suggested to you with "realtek" appearing first in the list. |
| 9 |
But this stopped working following an update to 5.4.x and is still the |
| 10 |
case today with the 5.6.x family (I keep testing it once in a while). |
| 11 |
|
| 12 |
I then decided to build both realtek and r8169 modules into the kernel: |
| 13 |
|
| 14 |
REALTEK_PHY=y |
| 15 |
CONFIG_R8169=y |
| 16 |
|
| 17 |
It did require a bit of faff as the whole chain of dependencies from |
| 18 |
REALTEK_PHY had to be built in as well, but I think that was about 5-6 |
| 19 |
kernel options in total. |
| 20 |
|
| 21 |
Adding it to the ramdisk as William suggests might work too. In my case |
| 22 |
I didn't bother trying this due to the fact that every failed attempted |
| 23 |
required manual intervention by someone to get the machine booted with |
| 24 |
working kernel. |
| 25 |
|
| 26 |
I have a gut feeling that tells me adding it to the initrd probably |
| 27 |
won't work. But if you're planning on trying it, please keep us posted. |
| 28 |
I would be very interested in hearing your solution. |
