Created attachment 303714 [details] dmesg Hello, First of all, my bluetooth adapter is; 04:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a) I see the following message everytime on tty when i boot the pc. "Bluetooth: hci0: Malformed MSFT vendor event: 0x02" But bluetooth + wi-fi is fully functional. And it seems to be a common issue with users who have the same hardware (Intel AX200). https://bbs.archlinux.org/viewtopic.php?id=276815
Same error, older hardware. see details below. ``` $ sudo dmesg [ 29.392310] Bluetooth: hci0: Malformed MSFT vendor event: 0x02 ``` ``` $ uname -a Linux jungle 6.1.14-hardened1-1-hardened #1 SMP PREEMPT_DYNAMIC Sat, 25 Feb 2023 13:15:09 +0000 x86_64 GNU/Linux ``` ``` $ lspci 3c:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78) ``` ``` $ lscpu Intel(R) Core(TM) i5-7Y54 CPU @ 1.20GHz ```
Same error on newer Intel hardware (AX210), since I've started using kernel 5.19.x (compiled by Ubuntu). My bluetooth keyboard and mouse also now need ~1 second when the desktop is loaded before being usable. With my previous kernel (5.15.x), this error message did not appear and I could use the keyboard right away, without the small lag that I now experience. $ lsusb | grep Bluetooth Bus 001 Device 002: ID 8087:0032 Intel Corp.

@Mathias, please create a separate issue for the regression also attaching the btmon logs with both Linux kernel versions. Please mention the bug report number in here. (Best would be, if you could bisect the regression. Ubuntu offers Linux kernel mainline builds [1], which make for a good start.) [1]: https://kernel.ubuntu.com/~kernel-ppa/mainline/
