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.
