I have to rebuild every new kernel because of the simple-drm module issue. I modify my config with the file /rpmbuild/SOURCES/kernel-local
kernel-local :
# This file is intentionally left empty in the stock kernel. Its a nicety # added for those wanting to do custom rebuilds with altered config opts.
CONFIG_FRAME_POINTER=y CONFIG_KGDB=y CONFIG_KGDB_SERIAL_CONSOLE=y CONFIG_KGDB_KDB=y CONFIG_KDB_DEFAULT_ENABLE=0x1 CONFIG_KDB_KEYBOARD=y
CONFIG_SYSFB_SIMPLEFB=y CONFIG_DRM_SIMPLEDRM=m # CONFIG_FB_SIMPLE is not set
