I would like to retract this again because it seems like the firmware is now
hanging all the time when the default runtime-pm/deep-sleep settings are used.

[ 521.553436] mt7921e 0000:05:00.0: Message 40000002 (seq 12) timeout

[ 521.723561] mt7921e 0000:05:00.0: Firmware init done

This doesn't seem to happen that often when I perform a

echo 0 > /sys/kernel/debug/ieee80211/phy0/mt76/runtime-pm
echo 0 > /sys/kernel/debug/ieee80211/phy0/mt76/deep-sleep

before setting up the interfaces.

But even then, on the first "ip link set up dev mon0" (not only for mon0 -
also for wlan0/...) it will crash with:


[ 806.731357] mt7921e 0000:05:00.0: Message 00000046 (seq 4) timeout

[ 806.928204] mt7921e 0000:05:00.0: Firmware init done

But when I then set up the device again then it seems to work. This is the
case for monitor and managed interfaces.

I've used commit 678071ef7029 ("mt76: mt7615: clear mcu error interrupt status
on mt7663") in mt76.git for this.

Kind regards,
