Red Hat Customer Portal - Access to 24x7 support and knowledge

hey, i am installing the realtime-kernel by

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_for_real_time/9/html-single/installing_rhel_9_for_real_time/index#doc-wrapper

after installed redhat 9.2.

and standard kernel

5.14.0-284.18.1.el9_2.x86_64

works ok.

but when i switch default-kernel to rt, it does't work.

redhat version: 9.2
realtime kernel -version : 5.14.0-284.18.1.rt14.303.el9_2.x86_64

error message is in the picture.

anyone know about it?

// i did't install

kdump
