Interesting that the d3cold_allowed change made some differences (I'm assuming it was failing 100% of the times before that change).
Few more questions. After a bad resume: 1) are there unkillable processes (D state) in the system (`ps axuw | grep D`)? 2) does `sudo iwlist wlp4s0 scan` return any error or does it hang indefinitely? 3) do you have bluetooth enabled (what's the output of `sudo rfkill list`)? As a temporary workaround you can automate the modprobe trick (#3) doing something like the following: $ cat /lib/systemd/system-sleep/iwlmvm.sh #!/bin/sh case $1 in pre) modprobe -r iwlmvm ;; post) modprobe iwlmvm ;; esac But it'd be nice to find a proper solution to this.
