Hi. I have also an Asus motherboard with a marvell controller for external sata drive. Since upgrade from lenny to squeeze, the external hd did not work. As it has also an usb connection, I can use it through usb, but if it is conncected to the marvell sata instead of to usb, boot hangs. Motherboard is M2V. Current kernel version is 2.6.32-5-amd64. Greatings. Eduardo Gross
