The only experience I have with a JMicron controller is an outboard eSATA docking station (a great product) and it uses the AHCI_SATA driver. I don't know what magic 'ahci' implies (Wikipedia tells you more than you want to know), but you might try that driver to see if your dmesg says anything different. Intermittent failures on bootup strongly suggest driver problems, in my experience. However, in my day the acid test was: does the hardware work on Windows? Thankfully those days are long gone ;)
