No, the iTCO_wdt driver won't fail to start. It actually depends on whether RCBA BAR is set. However, ICH9 will just ignore whether NO_REBOOT is set or unset when SPKR pin is high.
This is the code I was referring to, in iTCO_wdt_start:
/* disable chipset's NO_REBOOT bit */ if (iTCO_wdt_unset_NO_REBOOT_bit()) { spin_unlock(&iTCO_wdt_private.io_lock); pr_err("failed to reset NO_REBOOT flag, reboot disabled by hardware/BIOS\n"); return -EIO; }
