Hello,
Due to some issues after upgrading to linux58 (e.g. encountering black blank screen when system wakes up), I decided to downgrade to see if things change, I’ve got linux57 installed as well, so I used (Manjaro Kernels - Manjaro Linux):
sudo mhwd-kernel -i linux57
Which completes properly, but after reboot the 5.8 kernel is still used.
Packages (1) linux57-5.7.19-2

>>> NOTE, 5.7.19 was the last maintenance release by Greg Kroah-Hartman.
This kernel series is now marked EOL (end of life).
It is recommend to move on to linux58 series.
Use followed cmd to do that: 'sudo mhwd-kernel -i linux58'
