Title:
mt7921e wifi fails to resume after suspend
Status in linux package in Ubuntu:
Incomplete
Bug description:
After resuming my suspended PC, the wifi becomes unresponsive. The
only way to get it working again is to do a full reboot. I'm using
Ubuntu 22.04 LTS Jammy and my wifi card is:
MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz using `mt7921e` driver.
This is what I can see in the logs:
