Public bug reported:
After upgrading to Linux 6.8.0-38, Bluetooth adapter (USB part of the
Intel AX200) stops working after a few suspend/resume cycles. WiFi (PCIe
part) continues to work as expected.
Kernel log shows:
Bluetooth: hci0: Reading Intel version command failed (-110)
instead of the usual:
Bluetooth: hci0: Bootloader revision 0.3 build 0 week 24 2017

Bluetooth: hci0: HCI LE Coded PHY feature bit is set, but its usage is not
supported.
Bluetooth: MGMT ver 1.22
First appeared on 6.8.0-38, 6.8.0-36 and earlier worked without issues.
I suspect linux-firmware might be missing updates corresponding to changes in
the kernel driver or a regression was introduced in the update.
