I'm using Debian 13 and after the system updated to kernel version 6.12.88, my Bluetooth stopped working.

It shows Bluetooth: hci0: Failed to send wmt func ctrl (-22) error during bootup.

I tried all common troubleshooting and it didn't work.

After switching to Kernel 6.12.86, it works fine.
I'm using Mediatek Wi-Fi 6 7921 adaptor.

Is anyone else facing this issue?

Did anyone got Emergency alerts in Tamil Nadu? I have seen posts of people from other states getting test alerts but no one seems to have gotten them in Tamil Nadu.
