Due to CentOS website document cannot provide a simple instruction to build CentOS 8 stream with some easy steps. So, I make a note to record these procedures about how to build it.
Detail description and instruction, please refer to CentOS document, but if you have read the document and still don’t know how to do that, it can follow my instruction to build the kernel from CentOS 8 kernel source.

It’s a strange problem, after login kubuntu/ubuntu system, after a while, the mouse click won’t work anymore suddenly. but it still can move. original post is for ubuntu 18.04, but it’s also work on my ubuntu 22.04
How to solve it temporary ? reload the psmouse driver
sudo modprobe -r psmouse
Suppose the ACPI driver or UEFI cause this issue, but not easy to find it out.

猜測原理應該藉由中華電信內部設定會讓小封包先通行的設定，達到穩定 ping 值的目地

muttichase is a google open source tool which can run latency, bandwidth and loader-latency tool,
it can support both x86 and ARM64 platforms.
but it will have compile error on CentOS 8
root cause is this package needs static lib support, but regular CentOS doesn’t have it.

這個時間有點久了，我也忘了很多細節，畢竟用到的次數太少，不過就將記得的寫一篇，以後可以自己回來查資料
如果是有 BMC 的機器，BMC 內部有一個 watchdog 可以監視 host 系統運行的狀況，這個拿來放在遠端重啟 host 非常好用

This article’s procedure was tested in Ampere Altra CPU platform, but suppose that x86 system also can use this procedure.
CentOS 7’s gcc is too old to compile Linux kernel 5.x, and it can use another package named “software collections(SCL)” to install newer gcc to build Linux kernel.
