所以我在 NUC11PAHi5 上安装了 Debian 11 (Bullseye)。到目前为止,一切似乎都工作正常,但是今天早上,当我尝试配对一些耳机时,我发现蓝牙实际上无法工作。
在“设置”中,当我进入蓝牙时,它显示为关闭。我可以打开它,但改变的只是开关。如果我进入不同的设置窗格并返回,蓝牙会再次关闭。
uname -a

Linux NUCTUX 5.10.0-8-amd64 #1 SMP Debian 5.10.46-4 (2021-08-03) x86_64 GNU/Linux
当我跑步时sudo dmesg | grep tooth
,我得到:

其中failed to load intel/ibt-19-0-4.sfi (-2)
看起来像是我的问题的潜在原因,但搜索该消息几乎没有产生任何结果。
我最初在 UEFI 管理器中禁用了 wifi,因为我没有使用它,但打开它没有什么区别。
有人遇到过这个,或者有任何指示吗?提前致谢!
答案1
firmware: failed to load intel/ibt-19-0-4.sfi
这就是它不起作用的确切原因。
