Roughly a month ago I upgraded the kernel on my wandboard quad. The quad had been running
kernel 4.17.19-200.fc28.armv7hl and was working properly.
However, when I upgraded to kernel 4.18.5-200.fc28.armv7hl I found that ethernet no longer
worked. I reverted to kernel 4.17.19-200.fc28.armv7hl and ethernet was fine again.
I've tried several kernels since then, including the latest
(4.18.13-200.fc28.armv7hl), with the same negative result.
When running kernel 4.18.13-200.fc28.armv7hl the console messages say that the link is up,
however I am not able to ping anything on the local subnet.
I filed a bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1628209
Does anyone know of any driver changes that might account for this bug?
