This is the problem here. The L4Linux is trying to access port 0x110 but does not have the right to do so. Question is now which driver/subsystem is doing this so it can be disabled. Boot with initcall_debug=1 to hopefully see which driver it is and disable it in the config. Alternatively you should just start with a standard defconfig (x86-ux_defconfig or x86-native_defconfig).
