After upgrading my system to the latest stable release, my laptop cannot boot without going into grub and running the kernel using initramfs. The screen becomes corrupted and the system reboots continuously. I experienced a similar issue on Ubuntu, after which I installed Manjaro. It was fine until today, and I think it has something to do with the linux-firmware package because of the error I posted below.
