[ 447.601549] ------------[ cut here ]------------you should post this as issue to mt76 github with your exact version (openwrt/linux/mt76 driver).
update backports-5.15.33-1 to backports-5.15.92-1 and mt76-2022-09-06 solve this issue.
Hi,
I see the same issue with 23.05.03, BPI R3.
root@OpenWrt:/# modinfo mt76
module: /lib/modules/5.15.150/mt76.ko
license: Dual BSD/GPL
depends: mac80211,cfg80211
name: mt76
vermagic: 5.15.150 SMP mod_unload aarch64
May I ask how do you update the mt76? Does it require update of mac80211,cfg80211, hostapd, wpa_supplicant etc?
regards
Maybe, I shall rephrase the question like this: OpenWrt 23.05.03, with kernel 5.15.150, comes with MT76 driver:
(feel comfortable to correct me if Im wrong)

To get a up-to-date driver, or at least the working one as reported “mt76-2022-09-06”, what are the porting steps/procedures? How deep is the rabbit hole? Can anyone provide guidence/support on this?
regards
Try use 6.1 which should be default openwrt kernel now.
The issue stays with 6.1, even worse more frequent, including above, additional with a new crash as follow: same crash, call from another function I guess.

6.6 uses same mt76 at 6.1 - both have same build time. So, same situation I posted previously as in 6.1 happens in 6.6, openwrt current master.

[ 11.484977] mt798x-wmac 18000000.wifi: registering led 'mt76-phy1'
so, if anyone can point an example or any suggestion, I would like to give a try for the mt76-2022-09-06 mentioned above. or maybe the newer mt76s.
The built time is wifi firmware binary,not mt76 code version. But afair openwrt uses a nearly recent mt76 version instead of the kernels version which stays at some point and only gets fixes.
Update source to make sure latest mt76 is active and try again…if bug is still present look for issue in mt76 repo on github and if there is none report it
