Kernel 5.4 doesn't start after update but 5.10 it starts

[theodore]

Hi !

I just updated my Manjaro KDE sysetm with the latest 150 or so packages and kernel 5.4 doesn’t start anymore. Error: linux unable to mount root

But with kernel 5.10 it starts. I tried to reinstall 5.4 but the same error appears.
I prefer to use 5.4 because 5.10 doesn’t recognize my external monitor while 5.4 recognize it.

If someone could help me fix the monitor issue for 5.10 or the booting of 5.4 it would be great!

I have dual boot Windows/Mnajaro with Refind as boot manager.

Thanks for taking the time!

See this:

[Stable Update] 2021-06-14 - Kernels, Browsers, Mesa, Deepin, Systemd, Gnome Apps 40.2, Pipewire, Haskell

Every body who’s going to update keep in mind that you need to use linux510 or above in order to boot after this update. If you have only linux54 or below hold on your horses and wait for a fix from philm or simply edit /etc/mkinitcpio.conf with uncommenting of the line #COMPRESSION="gzip" after the update, then do sudo mkinitcpio -P and only then reboot. UPD: Ok disregard the above, philm nailed it.

I installed one more update and now 5.4 it works. Thanks!

How about why 5.10 doesn’t recognize my LG external monitor? (while 5.4 does)
There’s something I can do? Thanks!
