Instead make the root fs mounting look like this while(my_rootfs_hasnt_appeared_and_i_am_sad()) { wait_on(&new_disk_discovery); } and poke the queue whenever we add a relevant device. That way if you are booting off an initrd you can finish the SATA probe in parallel to getting userspace ticking over. On what is nowdays essentially a hot plug system it all needs turning this way up - eg RAID volumes should assemble and come online as the drives are discovered not at some fixed point later in userspace.Indeed, something like this should also be used for resume-from-hibernation, to wait for the swap device.
.. It just needs a way to set a finite timeout, so that server room equipment can auto-panic-reboot and try again if a device has died. -ml -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
