Not sure if this is connected with what you are seeing, but...
Something similar has been happening with SD cards on the OLPC laptop
(another example of hardware specifically designed for the FOSS world)
for at least the last six months. Last time I checked, there was still
no real fix. Has been a major pain for people who want to multiboot --
forces them to use storage devices that don't fit inside the case.
I am getting the impression that interfacing to SD cards is hard.
