It sounds like it is trying to mount the card as a ext2 file system.
I am not sure why that is. As far as the labels, you need to copy
the exact message - I don't think it is talking about file system

Dumb question - when you are trying to use fdisk, are you using
mmcblk0 or mmcblk0p1? You should be using mmcblk0.

You have a different chip set from the OP - you have the TI chip
set, and he has the Ricoh chip set. They use different drivers. I am
not sure why you are having problems with the TI drivers - they have
been working correctly in my Toshiba laptop. I forget the first
kernel that they started working without tweaking the registers
before loading the modules, but I think it was in FC6. You should
file a bug report because it may be something to your specific setup
and it will probably not be fixed otherwise - the developers do not
know there is a problem if the people it is not working for do not
file a bug report.
