Public bug reported:
This bug seems to be related to the following one:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/730820
Namely, when inserted, a card is recognized correctly, but after some
time starts to misbehave and the file system remounts as read-only. The
system in question is Ubuntu Natty, with kernel version
2.6.38-8-generic, on a Dell Latitude E6510. The memory card is Transcend
microSDHC, 16GB capacity.
Here comes the dump:
