作業系統完全凍結

從昨天開始，我的作業系統 archlinux 經常完全凍結，沒有明確的原因。

我唯一要做的就是在它發生時用 Firefox 瀏覽網際網路。

在這些凍結期間，音頻、藍牙仍在工作，但我無法與系統互動……

我試圖在系統日誌中找到一些有用的東西：

$ sudo journalctl -b -1 -k -xe

這些凍結在系統更新後沒有發生（上次更新大約是一周前），我更新了我的系統，試圖修復它但沒有成功。

我可以做些什麼來診斷並嘗試解決這個問題？

謝謝 ！

這可能與此處和此處討論的問題相同。

一個短期解決方案（也適用於我）是解除安裝xf86-video-intel.
