There is a fix proposal here: https://patchwork.linux-mips.org/patch/14041/ There is still few other boards remaining that use of_platform_bus_probe() from device_initcall, but who knows, maybe they are not affected. arch/microblaze/kernel/platform.c arch/mips/mti-malta/malta-dt.c arch/mips/netlogic/xlp/dt.c arch/x86/platform/olpc/olpc_dt.c A. > On 16.08.2016 17:00, Aaro Koskinen wrote: > > Hi, > > > > Commit 44a7185c2ae6 ("of/platform: Add common method to populate default > > bus") added new arch_initcall of_platform_default_populate_init() that > > will be called before device_initcall octeon_publish_devices().
