https://bugzilla.kernel.org/show_bug.cgi?id=215187 --- Comment #5 from Takahide Nojima (nozzy123nozzy@xxxxxxxxx) --- Hi Luiz, >Try renaming it then I copyed and renamed "intel/ibt-19-16-4.sfi" and "intel/ibt-19-16-4.ddc" to "intel/ibt-19-16-0.sfi" and "intel/ibt-19-16-0.ddc" respectively. After I rebooted 5.16-rc3 which has "iwlwifi-QuZ-a0-hr-b0-67.ucode", I found strange messages in dmesg. -------------------here----------------------- kernel: Bluetooth: Core ver 2.22 kernel: NET: Registered PF_BLUETOOTH protocol family kernel: Bluetooth: HCI device and connection manager initialized kernel: Bluetooth: HCI socket layer initialized kernel: Bluetooth: L2CAP socket layer initialized kernel: Bluetooth: SCO socket layer initialized kernel: iwlwifi 0000:00:14.3: firmware: direct-loading firmware iwlwifi-QuZ-a0-hr-b0-67.ucode kernel: iwlwifi 0000:00:14.3: api flags index 2 larger than supported by driver kernel: iwlwifi 0000:00:14.3: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.37 kernel: iwlwifi 0000:00:14.3: loaded firmware version 67.8f59b80b.0 QuZ-a0-hr-b0-67.ucode op_mode iwlmvm kernel: iwlwifi 0000:00:14.3: firmware: failed to load iwl-debug-yoyo.bin (-2) kernel: bluetooth hci0: firmware: direct-loading firmware intel/ibt-19-16-0.sfi kernel: Bluetooth: hci0: Found device firmware: intel/ibt-19-16-0.sfi kernel: Bluetooth: hci0: Boot Address: 0x24800 kernel: Bluetooth: hci0: Firmware Version: 125-46.21 kernel: iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz, REV=0x354 kernel: iwlwifi 0000:00:14.3: Detected RF HR B3, rfid=0x10a100 systemd[1]: Starting Bluetooth service... kernel: iwlwifi 0000:00:14.3: base HW address: b0:a4:60:b4:69:96 bluetoothd[637]: Bluetooth daemon 5.61 systemd[1]: Started Bluetooth service. systemd[1]: Reached target Bluetooth Support. bluetoothd[637]: Starting SDP server dbus-daemon[505]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.12' (uid=0 pid=637 comm="/usr/libexec/bluetooth/bluetoothd ") kernel: Bluetooth: BNEP (Ethernet Emulation) ver 1.3 kernel: Bluetooth: BNEP filters: protocol multicast kernel: Bluetooth: BNEP socket layer initialized bluetoothd[637]: Bluetooth management interface 1.21 initialized kernel: iwlwifi 0000:00:14.3 wlp0s20f3: renamed from wlan0 NetworkManager[664]: <info> [1639037359.3299] rfkill1: found Wi-Fi radio killswitch (at /sys/devices/pci0000:00/0000:00:14.3/ieee80211/phy0/rfkill1) (driver iwlwifi) NetworkManager[664]: <info> [1639037359.3363] Loaded device plugin: NMBluezManager (/usr/lib/x86_64-linux-gnu/NetworkManager/1.32.12/libnm-device-plugin-bluetooth.so) kernel: Bluetooth: hci0: command 0xfc01 tx timeout bluetoothd[637]: src/profile.c:register_profile() :1.71 tried to register 00001108-0000-1000-8000-00805f9b34fb which is already registered bluetoothd[637]: src/profile.c:register_profile() :1.71 tried to register 0000111f-0000-1000-8000-00805f9b34fb which is already registered systemd[1]: Stopped target Bluetooth Support. kernel: Bluetooth: hci0: FW download error recovery failed (-110) kernel: Bluetooth: hci0: Bootloader revision 0.4 build 0 week 30 2018 kernel: Bluetooth: hci0: Device revision is 2 kernel: Bluetooth: hci0: Secure boot is enabled kernel: Bluetooth: hci0: OTP lock is enabled kernel: Bluetooth: hci0: API lock is enabled kernel: Bluetooth: hci0: Debug lock is disabled kernel: Bluetooth: hci0: Minimum firmware build 1 week 10 2014 kernel: bluetooth hci0: firmware: direct-loading firmware intel/ibt-19-0-4.sfi kernel: Bluetooth: hci0: Found device firmware: intel/ibt-19-0-4.sfi kernel: Bluetooth: hci0: Boot Address: 0x24800 kernel: Bluetooth: hci0: Firmware Version: 191-21.21 systemd[1]: Reached target Bluetooth Support. systemd[724]: Reached target Bluetooth. systemd[1209]: Reached target Bluetooth. kernel: Bluetooth: hci0: Waiting for firmware download to complete kernel: Bluetooth: hci0: Firmware loaded in 1578507 usecs kernel: Bluetooth: hci0: Waiting for device to boot kernel: Bluetooth: hci0: Device booted in 14827 usecs kernel: bluetooth hci0: firmware: direct-loading firmware intel/ibt-19-0-4.ddc kernel: Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-19-0-4.ddc kernel: Bluetooth: hci0: Applying Intel DDC parameters completed kernel: Bluetooth: hci0: Firmware revision 0.0 build 191 week 21 2021 --------------------here----------------- As wrote above,the kernel loaded "intel/ibt-19-16-0.sfi" at first,but fails to load, finally it loads "intel/ibt-19-0-4.sfi" successfully. And more strange, I rebooted this kernel several times, I found the kernel became not to load "intel/ibt-19-16-0.sfi" and load "intel/ibt-19-0-4.sfi" from the beginning of boot. I'm not sure why the kernel suddenly began to load "intel/ibt-19-0-4.sfi". Does someone let known to me why, please? I guess it could be that "btintel.c" lacks some important sequence to AX201, an Example for resetting the device, or some prerequisite process. >I don't think the wifi firmware has any relation to the bluetooth firmware I wish the documents of the AX201 datasheet could show details.
