Hi, just an update about my previous post. The "pci=nomsi,noaer" workaround is effective for resume after suspend, but it locks my computer in resume after hibernation (the computer resumes, but it locks on resume with a black screen when it should instead show the login dialog; this probably happens for an interaction between "nomsi" kernel option and the nvidia proprietary driver, I suppose).
So that, I opted for the following simpler workaround: I created an hook in /lib/systemd/system-sleep (acording to systemd-suspend.service manual page) containing the following bash script: #!/bin/sh ## This file (or a link to it) must be in /lib/systemd/system-sleep/ modprobe -r sky2 modprobe sky When systemd resumes from hibernation or suspend the script is executed and the sky2 network card driver is reset. I hope this kernel bug would be solved soon.
