Hay Richard, if you've not already, try booting with the eSATA cable _not_ connected to the HBA and see if that prevents the lock up. If it boots, make sure both the server and disk box PSUs are both plugged into the same AC circuit, preferably the same UPS, and that all equipment shares the same earth ground, and give it another go. Having equipment like this on different earth ground paths can cause issues like what you're seeing due to voltage differences on the eSATA wire. Or, at least, this used to occur on occasion with external SCSI array boxen, so I'm guessing eSATA isn't immune given the interconnect is copper, not fiber. Replace the eSATA cable with a "known good" cable if you haven't already. Just helping you dot all the Ts and cross all the Is. I know I've overlooked small "simple" stuff on at least more than one occasion--happens to all of us at one point or another. Would you mind supplying the specific branded server or mobo model # so I can do some research on possible board and/or chipset errata, known bad card/slot combinations, etc? -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
