Linux laptop 4.15.0-48-generic #51-Ubuntu SMP Wed Apr 3 08:28:49 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Just upgraded from 17.10 to 18.04, sorry, I somehow didn't realize my laptop was still back on 17.10. Anyway, 17.10 suspend/resume was perfect. But after about 10 resumes on 18.04, the wired NIC does not come back ever. Not even once.
Currently running 4.15.0-48-generic and seeing this problem. Removing the 'sky2' module and re-adding it immediately fixes the problem.
$ ip a shows
2: ens1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
But the link light shows a good link and the activity shows activity as expected.
This is an HP ProBook 6540b.

I have not tried the GRUB suggestion here: https:/ /askubuntu. com/questions/ 1029620/ ubuntu- 18-04-lts- sky2-ethernet- stops-working- after-system- resume- from-suspend
GRUB_CMDLINE_ LINUX_DEFAULT= "quiet splash pci=nomsi,noaer"
Again, I have not tried this yet. Just putting it here for reference in case it does work.
