how to get kernel panic message logged?

Question

i am trying to build a custom Linux kernel for the Intel nuc board.

first of all i have installed clearlinux(a Linux distribution) on bare metal. Im trying to install the custom Linux alongside the clearlinux by placing the kernel in /efi/boot and the added a entry in /efi/loader/entries . Im using systemd as my default boot loader.

Im getting kernel panic while im trying to boot the custom linux. The problem is i couldn't see the entire message in my console.

is there any way that i could load the message in to a file and viewenter code here or could add some options to the kernel parameters so that i can navigate through the entire kernel panic text

here is my kernel entry

title customoslinux 
linux /EFI/custom/bzImage 
options root=PARTUUID=0de21747-3184-47eb-a415-720247c9abc6 quiet console=tty0 console=ttyS0,115200n8 init=/usr/bin/initra-desktop

You may add "vga=ask" to your kernel commandline and before kernel start it will ask you for screen resolution. Just choose some big resolution and start the kernel.

that option doesn't seem to work. kernel not seem to recognize that command. – Jagadish DM Oct 23 '18 at 14:48
If you are able to connect serial terminal - do it - it is the easiest solution. If not - you can recompile the kernel adding vga=ask option. – user2699113 Oct 24 '18 at 03:59
