dmesg of 12.1 GENERIC kernel running on 12.2 system
Radeon HD 5450 causes kernel panic after upgrade to RELEASE 12.2 with GENERIC kernel, /etc/rc.conf is using kld_list="/boot/modules/radeonkms.ko", installed drm-kmod-g20190710. Only way to boot 12.2 kernel is to comment out the kld_list line from /etc/rc.conf. Currently running old 12.1 GENERIC kernel on updated 12.2 system -- strange but it is working.
Other info that might be important.
/boot/loader.conf has only 1 line: amdtemp_load="YES"
When running the 12.1 kernel on the 12.2 system, I am using the Radeon card & kld_list.
When running the 12.2 kernel on the 12.2 system, I am using the motherboard graphics without kld_list.

(In reply to kenneth.freidank from comment #1)
Please disregard comment #1. I am running the 12.2 kernel on the 12.2 system, however the display is no where as crisp as when running the 12.1 kernel with the kld_list="/boot/modules/radeonkms.ko" in the /etc/rc.conf.

Does build drm-kmod from ports help? Please refer to bug 250700 (comment #1) for more information.
No. I installed drm-kmod from a poudriere build in a 12.2 Release jail and a new ports pull. I built using the 12.2 kernel (remember I kept the old 12.1 kernel in the boot menu). I un-commented "kld_list=/boot/modules/radeonkms.ko" and the kernel panicked.
I only removed drm-kmod when installing my previous build. A "pkg info | grep drm" showed 3 drm packages, and a "pkg info | grep kmod" showed 1 additional package. I removed all 4. After this, I changed to graphics/drm-kmod, did a "make clean", and "make install". I did not try using the Poudriere builds again.
I restored my rc.conf line and I have my graphics back.
Side Note: I completely rebuilt and installed 12.2 RELEASE world with GENERIC from releng.
