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).

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.

@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.)
