Interesting :-)
But the linaro-media-create "size" output is probably broken for the same reason: sdb appears to be unavailable for some time after changing the partition table:
Are you 100% sure, on selecting [/dev/sdb] (y/n)? n r65073@S2101-09:~/image/linaro$ sudo parted -s /dev/sdb mklabel msdos && sudo sfdisk -L /dev/sdb /dev/sdb: No medium found
sfdisk: cannot open /dev/sdb read-write
That's pretty convincing to me; anything relevant in dmesg?
We could do something like the attached shell script; would you mind running it to confirm this works without removing/reinserting the MMC? I'm curious to see how much time your drive needs to come back.
