If function_graph tracer is enabled during kexec, we see the below exception in the simulator: root@(none):/# kexec -e kvm: exiting hardware virtualization kexec_core: Starting new kernel [ 19.262020070,5] OPAL: Switch to big-endian OS kexec: Starting switchover sequence. Interrupt to 0xC000000000004380 from 0xC000000000004380 ** Execution stopped: Continuous Interrupt, Instruction caused exception, ** Now that we have a more effective way to completely disable ftrace on ppc64, let's also use that before switching to a new kernel during kexec.
