Done ...

What’s the output of

mhwd-kernel -li


Currently running: 5.15.12-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux515

i got this

Try now:

sudo mhwd-kernel -i linux515-rt

And before that clean the cache @BlackHole :

sudo pacman -Scc
sudo mhwd-kernel -i linux515-rt                                                                                                                             ✔ 
:: Synchronizing package databases...
error: failed to synchronize all databases (unable to lock database)
error: failed to init transaction (unable to lock database)
error: could not lock database: File exists
  if you're sure a package manager is not already
  running, you can remove /var/lib/pacman/db.lck

Do a reboot and run

sudo rm /var/lib/pacman/db.lck
sudo pacman -Scc && sudo pacman -Syyu
sudo mhwd-kernel -i linux515-rt

done , now what? :sweat_smile:

Reboot and select the kernel from advance options of grub

i think its fixed. can i install 3 kernel ?

Yes, I have 3 installed myself.

This is the beauty one of the beauties of Manjaro.
