Thanks @bulislaw for reporting this. Why the CI did not report this, did we miss something?

We need to be careful with this type of changes. Note taken.

[bulislaw]

Yes :) We're missing WiFi tests and the EMAC is disabled by default. #3147

[geky]

Changes like those are always a minefield, sorry for the trouble.

[bulislaw]

Yeah, especially with a binaries in the sources, that's why I want to have tests for Odin. #3147

Fixed via #3221
