Modified Files: src/sys/dev/hil: hil.c Log Message: Fix "stray level 1 interrupt" panic by pressing keys during autoconf(9). Also explicitly initialize sc->sc_status = HIL_STATUS_BUSY in hil_attach(). Previously hil_intr(9) returned immediately during 'cold', but all interrupts are enabled at the end of configure() (actually in MD cpu_configure()) and cold is cleared in confiugre2() after configure(), so there is a small window when hil interrupts can be triggered during cold. It looks there is no problem to process hil_intr() before hil_attach_deferre() is called via configure2() because we already check 'sc->sc_status != HIL_STATUS_BUSY' on processing a kthread. Note this seems also to appease the similar panic on mame's hp9k370 emulation (though mame's emulation around DMAC looks still incomplete). Should be pulled up to netbsd-10 and netbsd-9.
