各位大佬好，我最近遇到了一个头疼的问题，想请大家帮忙支支招。我买了一块Intel AX210NGW无线网卡，当前用的是Pop!_OS 22.04系统，内核版本是6.2.6。WiFi功能完全正常，速度也拉满了，但网卡自带的蓝牙控制器却完全找不到——不管是冷启动（从BIOS开机）还是热重启，dmesg里搜不到相关信息，设备列表里也没有它的影子。我确认网卡是正品，不是山寨货。

我已经试过了能找到的几乎所有办法，包括直接从kernel.org的git仓库拉取最新的linux-firmware，但还是没用。我不想换内核，除非实在没办法。另外我对Linux内核了解不多，也不确定这是不是内核bug，或者是某个版本开始的回归问题。

下面是我收集到的系统信息，麻烦大家帮忙看看：
