Can you try this change:
diff --git a/sys/dev/ichiic/ig4_iic.c b/sys/dev/ichiic/ig4_iic.c
index a556127..23bdb7d 100644
--- a/sys/dev/ichiic/ig4_iic.c
+++ b/sys/dev/ichiic/ig4_iic.c
@@ -117,7 +117,10 @@ set_controller(ig4iic_softc_t *sc, uint32_t ctl)
error = 0;
break;
}
- mtx_sleep(sc, &sc->io_lock, 0, "i2cslv", 1);
+ if (cold)
+ DELAY(1000);
+ else
+ mtx_sleep(sc, &sc->io_lock, 0, "i2cslv", 1);
}
return (error);
}
