Critical boot failure on RPi 3

[oliverbrandt]

After finally having set up a test environment, the following problem occured on an RPi 3: https://gist.github.com/oliverbrandt/ec66ed2d7229d62f915e69a8124dab25

As I am not familiar enought with the ARM and AROS world, do you happen to know why this would happen or where to start searching for the cause?

The problem is asm volatile("mov r0, #0\n\t mcr p15, 0, r0, c7, c0, 4":::"r0")
in arch/arm-native/exec/exec_idle.c which is not supported in ARM v8.
Changing it to asm volatile("wfi") works.
According to http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka13332.html this should also work on ARM v7.
