No boot messages after kernel upgrade from 4.14 to 6.1

[boerns]

Hi, I need to switch from the old stable kernel grom gentoo-sources to the new one. I manged to build in all the things my workstation needs. A simple make odconfig was not the first and second succuessfull way, but after comapring the .config files and searching in "make xconfig" I finally could manage to get my gentoo box booting and having all drivers back available.

What I am missing, is messages at boot time from kernel or the starting daemons I have activated.

I only see a black screen until the xserver login comes up. Looks nice, but not what I want.

How can I reneable the "old begaviour". I realized that recent Linuxes like Debian 9-12 or RHEL7-9 also only show nothing or a splash screen or logo. But I am a traditional and would like to see the boot mesaget in 80x25 like before.

I tried to activate FB in the kernel and checked some settings in grub.conf, but did not fopund the root cause.

Any hints? Googling only shows for ready made linuxes how to bring it back but that I tried.

My last unsucuessfull try was to set on the linux command line "debug" but that made the kernel not boot at all and I need to revert back....

Any hints for a gentoo linux with recent serlf compiled kernel?

There is dmesg which should help.
Also there should be a kernel option called something framebuffer.... I think this old thread could help: https://forums.gentoo.org/viewtopic-t-1083076-start-0.html

boerns,

if a "make oldconfig" is not successfull you really should do a completely new configuration of your new kernel. (I suggest 6.6 because it is already LTS and will be the next Gentoo stable in the near future).

Please note: You can check your needed modules not only with your old .config, check it also with a "lsmod" after booting with GentooLiveCD.
