The JMicron BIOS isn't enabled. The behavior here is strange, the controller reports a connection status change interrupt with CommWake which should indicate that some device completed the handshake with the controller, but then the SATA link shows down. I assume there's nothing plugged into the two JMicron SATA ports? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
