Description Chatty 2017-03-24 21:27:03 UTC 
Description of problem: Rawhide crashes when going into standby. Hard reset needed to get out. Wifi rarely connects. Even if it disconnects after seconds and then reconnect becomes impossible.

How reproducible: easily


Steps to Reproduce:
1a. Let system drift off into Standby
1b. Connect to WPA2-encrypted Wifi


Actual results: Crash / disconnects


Expected results: Resume from standby / stable Wifi connection

Just retried with Fedora-Workstation-Live-x86_64-Rawhide-20180220.n.0.iso on a Surface Book with updated UEFI (microcode now 0xc2):

Connected successfully to WPA2 wifi.

Suspended successfully via "systemctl suspend" a few times (so Suspend now works) but still after few suspends wifi went crazy (see attached dmesg output). No way to reconnect to wifi - can't see networks anymore.
