突然、 Wi-Fi を認識しなくなった
今日、家に帰ってきたら GPD Pocket3 (UbuntuMATE 22.04) が突然 Wi-Fi を認識しなくなった。
ネットワークマネージャのインタフェースリストにも表示されない。
ワイヤレス接続のカテゴリ自体が表示されない。
ifconfig でも

ワイヤレスインタフェース（wlp174s0）がない。
どうも、デバイスそのものを認識できていない様子。
夕方にカーネルのアップデートをしている。
どうもそれが怪しい。
点検
ネットで情報を拾っていくつかのチェックを行ってみた。

最後の部分に

iwlwifi 0000:ae:00.0: WRT: Collecting data: ini trigger 13 fired (delay=0ms).
iwlwifi 0000:ae:00.0: Failed to run INIT ucode: -110
とあるし、最初のほうから丁寧に読むと、どうやらこれ全体がエラーログダンプっぽい。
いっぽう

（後略）
pciデバイスの存在は認識しているよう。
しかし
root@host:/home/user# rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
こちらはまったく認識していないよう。
いよいよこれはハードウェア的な故障ではないかと思える。
GPD Pocket3 もついに買い替えか? と思って身構えた。
しかし、やはりまずはカーネルモジュールの問題を疑っていくべきだろう。
さらにネットで調べた
参考になりそうな情報は
https://bbs.archlinux.org/viewtopic.php?id=275114
https://forum.endeavouros.com/t/intel-ax210-wifi-not-starting-upstream-bug/24560/7
https://bugs.archlinux.org/task/73387
である。
カーネルモジュールにバグがあるらしい。
これらの情報によれば
/lib/firmware/iwlwifi-ty-a0-gf-a0-66.ucode.xz
/lib/firmware/iwlwifi-ty-a0-gf-a0-67.ucode.xz
/lib/firmware/iwlwifi-ty-a0-gf-a0-68.ucode.xz
あたりを消すか、リネームすればよいらしい。
早速、試した
