Update: seems fixed on Linux kernel 6.0.9 / 6.1, commit 1598bfa “platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi”
TL;DR The temporary fix is either blacklist the kernel module hp_wmi currently, or comment out codes that provides rfkill function in that module.
Recently Windows auto-updated the BIOS of my laptop HP Elitebook 865 G9 to (U82) 01.02.01 Rev.A,
then in Linux the wifi and bluetooth device keeps on and off, seems 1-2 time(s) per second,
and character ^@ of unknown source keeps being inputed, even in emergency mode
(which make it almost impossible to type in password for root, thus cannot access root shell.)
This is the nth time I try to build a site.
If I have enough time, I will post some use(ful/less) informations here.
Hope I can do that, though I know it’s IMPOSSIBLE.
Update (2022/03/19) : removed some words because of Gitee’s nonsense content checker, but no use.
I have built a Minecraft server (1.9) on my Raspberry Pi, but brcause of the poor CPU (1 GHz), it may be VERYslow.
I haven’t built a server city in it, even I haven’t tested yet, and you can hava a try :-) .
