Wow, that came out as a real mess.
I used Outlook.com to compose that message.
Anyone experience that and can recommend how I can clean it up?
I see that I composed using "Rich Text".
I'll try to redo it in my reply here using "Plain Text":
Plain text is the right text formating.
"saveenv" won't write the environment out to disk.

Ignore the "unrecognized filesystem type" stuff. I'm using ext4.
mmc hwpartition only used for eMMC?
Yes, only eMMC.

I tested the latest mainline HEAD on U3, rev.0.2, on some two cheap
Sandisk 4GB SD cards. It works fine for both
Maybe your card is little tired and need some more timeout for some
operations, this could be the reason of that issue.
Can you test a different card?
