Hi,

after upgrading from 5.14.0-9.2-liquorix-amd64 to 5.14.0-9.3-liquorix-amd64 (Ubuntu 20.04.3 LTS), my NIC is not recognized anymore on Asus ROG MAXIMUS XIII APEX. Is this a liquorix or upstream issue?


Cheers,

Ok, is there any information you can provide about your system or any logs? Output of inxi -b on a working kernel (and also not), will help, and any related output from dmesg or journalctl -k.

And to be clear, the update to 5.14.0-9.3 enabled tracing options and merged some release candidate stable patches. Reviewing the patches there's nothing network related.

Hi,

the issue persists with 5.14.0-9.4-liquorix-amd64. Here's some info, please let me know if you need more.

With 9.2 kernel:

Ok, thanks for the extra information. It looks like a release candidate stable patch was making CONFIG_IGC incompatible with the 5.14 kernel configuration, so it erases it on "make oldconfig".

I reverted the problematic patch and re-enabled the config for IGC. Next release should be out in 2 hours with fix included.
