excerpt from /var/log/message with log entries produced on resume
Hi,
Briefly:
I've got ThinkPad t480s. With it's Intel 8265 resume/suspend have always worked
reliably all the way from 12 throughout 14 versions. The only issue was low
speed. Hence after 14.3 was out decided to replace it by AX210 module. Overall
very happy with the latter too except WiFi completely stops working after
resuming from suspended state: neither connects to AP nor sees any APs around
(ifconfig wlan0 list scan produced empty output).
Straightforward measures like "ifconfig wlan0 down && ifconfig wlan0 up" or
"service wpa_supplicant restart wlan0" execute w/o errors however do not help
and never bring it back to operational state. The simplest workaround that I've
found so far to make it work again without reboot is to "service netif restart
wlan0 lagg0" (please, do not pay to much attention to lagg0 I believe it has
nothing to do with the issue. It's just a peculiarity of the local setup where
wlan0 is configured as a fail-over interface (laggport)).
Thus a simple devd rule + tiny script that recreates wlan0 interface are used
as a workaround for the time being. However the issue is worth consideration
and fixing I believe.
