Hello.
I recently installed ArchLinux on my new laptop. It looked like everything was fine except for my Wi-Fi network connection.
It keeps periodically disconnecting and reconnecting. No matter which network I used.
So I looked in my kernel log and it turns out the firmware keeps crashing and resetting hardware.
I appreciate any help. Thank you.
By the way, this is my first time posting on ArchLinux Forum. So any advice to improve my question is also very appreciated.
My logs and hardware information are below. Also the gist is available here.
My laptop is Lenovo ThinkPad E14 Gen5 with Intel 13th generation CPU.

Solved.
Create /etc/modprobe.d/rtw8852be.conf and write these lines:
options rtw89_pci disable_aspm_l1=y disable_aspm_l1ss=y
options rtw89pci disable_aspm_l1=y disable_aspm_l1ss=y
options rtw89_core disable_ps_mode=y
options rtw89core disable_ps_mode=yAfter reboot it stops crashing.
