Hi all!
I'm working on a embedded system (ARM) running from a SDcard. Recently I
switched to a btrfs-raid1 configuration, hoping to make my system more
resistant against power failures and flash-memory specific problems.
However today one of my devices wouldn't mount my root filesystem as rw
anymore.
The main reason I'm asking in this mailing list is not that I want to
restory data. But I'd like to understand what happened and, even more
importantly, find out what I have to do so that something like this will
never happen again.
Here is some info about my system:

You can also find the output of dmesg in the attachment.
How would you proceed in investigating this problem? Or do you already
see a problem in the dmesg output? (I'm not a very experienced linux user).
Best regards
Robert

Oh... looks like the attachment got lost... So I will post the output of
dmesg below. The SDcard related errors seem to start from timestamp (or
whatever that is in the brackets) [ 12.021717].
