[已解决] Thinkpad X1 Carbon Gen 13 蓝牙不工作, 加载固件失败

更新:

更新 linux-firmware 20250311.b69d4b74-3 后问题得到解决.

---

我在 Thinkpad X1 Carbon Gen 13 上安装了 Archlinux 和 KDE, 并且设置了和 Windows 的双启动. 在 KDE 设置里蓝牙不能启动. 我执行命令

 bluetoothctl devices 

他显示

No default controller available

以下是一些我电脑的信息

$ lspci

... ...
00:14.3 Network controller: Intel Corporation BE201 320MHz (rev 10)
00:14.7 Bluetooth: Intel Corporation Device a876 (rev 10)
... ...

rfkill list 的结果是

0: tpacpi_bluetooth_sw: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

Bluetooth service 正常工作, systemctl status bluetooth

btusb 模块没有在启动时加载. 然而我加载模块后, 蓝牙依然不正常工作.

modprobe btusb
systemctl restart bluetooth

我注意到 journalctl -b | grep Bluetooth 的报错

... ...

... ...

而且我在 "/lib/firmware/intel/" 里找不到 "ibt-0190-0291-pci".
