I have a script [1] that daily builds google cloud VM images with a fresh vanilla
kernel for postgres CI testing. The last successful image creation was
7ebfc85e2cd7b08f518b526173e9a33b56b3913b
and the first failing was
69dac8e431af26173ca0a1ebc87054e01c585bcc
Since then creating a new kernel boots but network does not come up.
Looking at the merges between those commit makes me suspect this merge:
