I have two machines (out of a group of ten) that will not bring up their ethernet interface at boot time if the interfaces is of type “allow-hotplug”. When I change that to “auto” the interface comes up at boot with no problem…
The remaining eight machines have no problem with allow-hotplug. (which is the default as setup by the d-i) It does not seem to correlate to kernel version. The two “auto” machines are running 4.12 and 4.9; The “allow-hotplug” machines are running anything between 3.16 and 4.12. Nor does it seem to correlate with static vs dhcp. The two “auto” machines are both using dhcp. The “allow-hotplug” machines are using a mixture of static and dhcp. Anybody have a clue as to what’s going on? Thanks in advance… Rick
