It happan on my DX58SO board too... BIOS ver. 86A.5529
After connect e-sata HDD, system won't boot up.
Have tried PSU, latest Bios update. Looks like a faulty board at this stage.
Do you have the Latest Marvell drivers , thats what runs the Esata.
Damm! Looks likely it is part of the Intel recall issue. Bugger! Hope they have this fix worked out asap
