我不是 Ubuntu 专家，但在使用内核更新实用程序将内核从 v4.15 更新到 v4.19.1 以解决该failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware -22问题后，我遇到了同样的问题（请参阅帖子https://www.reddit.com/r/Ubuntu/comments/8sllc2/wlp58s0_failed_to_remove_key_1_ffffffffffff_from/）。
这可能是由于 MS 开发的主板 BIOS/UEFI 中的 ACPI 代码与新的 Linux 内核发生冲突。请参阅此帖子：https://www.linuxquestions.org/questions/linux-hardware-18/acpi-error-what-means-4175605357/。
除了启动屏幕上出现一堆消息外，我没有发现任何差异。我将尝试不同的内核版本，看看问题是否消失。稍后将更新此答案。
