Description Victor Trac 2016-09-13 01:02:23 UTC

Description of problem:
When closing the lid to suspend my laptop, resuming does not work under linux 4.8. 

Version-Release number of selected component (if applicable):
4.8.0-rc5-mainline. Problem started with 4.8.

How reproducible:
Always

Steps to Reproduce:
1. Close lid. 
2. Open lid. 

Actual results:
When the lid is closed, the laptop tries to suspend. After waiting a few minutes, I can still hear the fan running and the laptop is still generating heat (found out by having it in a bag). If I open the lid, the laptop screen flashes a few times, and after a longer than expected time, GDM pops up and lets me login. However, everything seems a bit corrupted - I can open new terminals in gnome-terminal, but any 'sudo' command hangs forever (and ignores ctrl+c) and nothing (tabs, windows, etc) is clickable in chromium.  A 'reboot' command immediately shuts off the screen but hangs forever without actually rebooting.

Expected results:
Laptop suspends and resumes as previously in 4.7.x.

Did you report this to some list? linux-wireless (https://wireless.wiki.kernel.org/en/developers/mailinglists ) maybe? FWIW, "./scripts/get_maintainer.pl drivers/net/wireless/broadcom/brcm80211/" outputs this:

That might be the better approach to get attention…
