滚动更新升级内核后无法开机

今天升级了一下,内核从 5.9 升级到了 5.10.1,无法开机。能显示开机动画,但一直卡住没有变化。能在 Grub 里用旧内核启动,也能使用 LiveCD。

不光是你,很多都遇到了。kernel 5.10 有很多严重 bug 。

TG 群顶置消息:

Intel AX200 网卡用户在升级到 5.10 内核后可能会遇到 workqueue lockup 导致无法启动的 bug,参见:
https://bugzilla.kernel.org/show_bug.cgi?id=210733
https://bugzilla.suse.com/show_bug.cgi?id=1180344
目前可以通过在 /etc/modprobe.d/99-local.conf 中添加如下内容来解决:
options iwlwifi enable_ini=0
或者使用老内核启动。

但为啥 Live 镜像又是 OK 的呢?(虽然我已经开始重装了)

自从换了 AMD 都不敢轻易升级了…

我也是遇见过几次 bug 后就只用 lts 了

可能是因为 Live CD 没有 kernel-firmware:

iwlwifi 驱动在 kernel-firmware 里:
