Bug#1031839: network devices do not work after kernel upgrade
Hi Daniel,

Can you rule out that you were hit by the "interface names
changed"-problem (here, enp* changed to ens*)? Between 5.x and 6.x this
cought us a couple of times by surprise too..
yes, the enp*/ens* interfaces are handled by driver igc.
They are "normal" 1 Gigabit interfaces and are working fine, independent
of the kernel version.
The problem is related to the 10GB interfaces that are handled by module
ixgbe. They are called eno*.
The first log shows the not working kernel 6.x and the second part shows
the working kernel 5.x. "ip a" shows in the first case "no-carrier" and
all LEDs of that interface remain off.
