The last of these(May 31) does not fix sda1/sda2 to the uSD/SD, so multi-boot setups will may fail when an external USB drive is attached at boot time.

I have retested a multiboot with the May 31 uboot and am not finding any problems with sda/sdb not being fixed however hard I try.

I know sdc floats around between usb/esata but that's always been the case.

Under what conditions are you finding that they are not fixed?

2 cases - where the usb becomes device 0

1) Samsung 2TB drive ("Samsung  STORY Station")
2) A Huwaei 3G modem with internal flash drive

I don't know whether the problem is for May 31 ONLY. It is just that the above devices are on Dreamplugs using May 31.
In both cases  >> usb start / fatinfo /fatls,  was used to check on device 0.
Unfortunately, neither of these devices is in my possession.

I've written up a mechanism to boot in a known sequence including eSATA

I had a problem and what I discovered might be of help to others.
Perhaps this is a change with the newer DreamPlugs that are being shiped:
The internal SD card comes with 3 partitions.
Only the third is fat and I'm not sure what it's function is: it contains rootfs.tar.gz,  uImage, and  uinitrd
The first, and this is the important bit, is ext2 and also contains uImage but a diff of the uImages on the third and first partitions indicates that they are not the same.
The second partition is ext3 and contains the file system.

Your instructions had to be modified slightly as follows:
setenv boot_sdb 'fatload usb 1 0x6400000 uImage; bootm 0x6400000;'
had to be replaced by
setenv boot_sdb 'ext2load usb 1 0x6400000 uImage; bootm 0x6400000;'
and then all worked well.

I hope this helps to save others some headaches!

This ties in with another thread:
...the image and it seems to contain three overlapping partitions - not a good start!

It would be worth checking that the end of the first partition is correct. It should end before the second.

I've no idea what has been left in the third partition - maybe a previous uImage?
