我有一个戴尔 G7 7590笔记本电脑。我正在运行：
Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal
和内核：
5.8.0-050800rc7-generic #202007262231 SMP Sun Jul 26 22:33:51 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
我的 WiFi 每天大约崩溃两次，我的笔记本电脑每天死机一到两次（有时会挂起，有时需要完全重启）。
这几乎总是伴随着系统日志中的大量iwlwifi输出（我假设是因为它崩溃了）。
我懂了一个类似的问题。我正在使用rc内核，因为我遇到了与通用内核相同的问题，并且我需要测试新的热管理。
鉴于我拥有最新的硬件、操作系统和内核版本，有人能帮我找到这个极其令人沮丧的问题的答案吗？
syslog这篇帖子的末尾粘贴了部分冗长的输出。我认为问题发生在 16:24 左右。完整日志如下这里
其他请求的输出是：
