Installation

Microcode

Microcode update for AMD Ryzen 7 5825U has not been released yet. You can verify this information in an existing system by checking the family and model of your CPU and comparing it to the available patches from amd-ucode README:

# journalctl -b | grep smpboot

To resolve this, instead of using amd-ucode package, use amd-zen-ucode-platomav^AUR which includes the relevant patches.

Firmware

On every boot, wlan0 and bluetooth are blocked by rfkill(8), due to the ideapad_laptop kernel module. To resolve this issue, you can create a blacklist file:

/etc/modprobe.d/rfkill_fix.conf

blacklist ideapad_laptop
