Product: Drivers

Hardware: AMD
OS: Linux

Assignee: [email protected]

and now my dmesg is full of:

[   10.704037] Bluetooth: hci0: Invalid exception type 03

My hardware is:

Bus 003 Device 002: ID 8087:0025 Intel Corp. Wireless-AC 9260 Bluetooth Adapter

I've also updated from 6.14 to 6.15 but I feel like this is down to firmware.

With the new firmware, I received dozens of messages per hour.
