Description
OpenWrt 21.02 commit https://github.com/openwrt/openwrt/commit/0e0192098a52568d46bdde48a5749f13d3093fc5
Wifi stops working after 3-4 minutes loading of ubuntu iso via torrent. There is a message in the log after 'wifi down' command:
mt76_wmac 10300000.wmac: MCU message 08 (seq 1) timed out
The same problem on 21.02.1, but needs more time for triggering. All works fine on 19.07.8 version
WiFi config:
/etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option path 'platform/10300000.wmac'

option device 'radio0'

Research direction
Reproduce the failure on an MT7628 using the supplied OpenWrt 21.02 configuration and sustained torrent download, watching for the mt76_wmac MCU message 08 timeout after wifi down. Compare behavior with OpenWrt 19.07.8 and the linked 21.02 commit; the issue is resolved when WiFi remains usable under the workload without that timeout.
