Jul 19 07:21:34 ameagari kernel: Root mount waiting for: usbus7 usbus3 Jul 19 07:21:34 ameagari kernel: Trying to mount root from ufs:/dev/ad10s1a In this case, the delay is insignificant, however with some systems this can take up to 10 seconds. And we don't even need to wait for USB bus because the root filesystem is on an ATA hard disk. -- Kamigishi Rei KREI-RIPE
