This might be the work of CONFIG_PANIC_ON_SCHED_BUG which is extra debug
option enabled in *sdm845_defconfig*. You can disable it or better
I would suggest to use *sdm845-perf_defconfig* instead of
sdm845_defconfig since there are a lot of debug options enabled
in the latter which may be not compatible when IPIPE patches
are applied.
Thanks,
Sai
