Confirmed that rmmod of the brcmfmac module resolves the issue, and I'm able to suspend/resume as expected. Then please file another bug report to the brcmfmac driver people. Bug closed. |
Created attachment 232631 [details] full dmesg Description of problem: When closing the lid to suspend my laptop, resuming does not work about 20% of the time. The laptop is then frozen and I have to switch it of (pressing the power button a longer time). 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.
