Hello,
I am currently trying to set up Fedora 28 on a HP EliteBook x360 1030 G2
and everything is working quite nicely. My main problem is with the WWAN
card (HP lt4120, 03f0:9d1d) which, currently does not seem to work
correctly after a cold boot, but which is OK after a warm boot
(restart). I suspect a timing issue or some initial configuration that
does not get done upon cold boot, but do not know where to start
searching. I tried to attach both logs (journalctl) but did not see the
mail appear. Here are a few lines which seem significant to me. It seems
as if the device gets rediscovered again and again:
