Created attachment 304139 [details] Dmesg log for hung system Since Linux LTS 6.1.21, I got system hang from time to time (see 0326-6.1.21-1-lts.txt for one captured dmesg log) when I'm using my MT7610U chip as AP. lsusb reports the wireless adapter as 0b05:17d1 ASUSTek Computer, Inc. AC51 802.11a/b/g/n/ac Wireless Adapter [Mediatek MT7610U]. The system is Arch Linux. I'm using NetworkManager 1.42.4 and wpa_supplicant 2.10 for setting up the AP.
Created attachment 304140 [details] Lockdep log for a possible deadlock Lockdep shows there are possible deadlocks. The attached log is for 6.1.23, and I got similar logs on 6.1.15, 6.1.20, 6.1.21 and 6.1.22 as well.
Sorry, had missed this report earlier. Does this problem still happen? BTW, would be good to know if this happens with 6.3 as well.
I still got lockdep warnings with 6.2.11 and 6.3. I got no more hangs with 6.2.11 after using it for several days. Not sure if those lockdep warnings are false positives or not.

Please allow me one more question before I contact some developers then: do you still care getting the bug fixed in 6.1.y? Or will you stay on newer kernels anyway?
I'm fine with moving to 6.3.x, assuming lockdep warnings are false positives.
This happens again with 6.6.12-1-lts, so the bug is probably still there, just more rare. I will try 6.7 and see if I can get the bug there. Should I also upload a new dmesg log for 6.6.12-1-lts? Logs for different kernel versions seem quite similar. I'm not sure if more logs are helpful or just adding noises.
