 A manual bisection pointed to the following commit:
 
   2017.06.21.21.55.07 christos src/sys/arch/x86/x86/ipmi.c 1.65
 
 This looks like an over-eager conversion of printf() calls to
 aprint*().  The last version to boot successfully prints the following
 message on boot, by means of printf():
 
 [   1.1145740] ipmi_map_regs: bus_space_map(..., 0, 2, 0, 0xffffffff81a24ba0) failed
 
 In 1.65, this was changed into aprint_error_dev(sc->sc_dev, ...), but
 the call takes place at the driver match stage where sc->sc_dev is NULL.
