Carlos,
this looks like it could be an issue with the fat file system
handling a somewhat large filesystem. I have CCed the maintainer
for comment. I have looked through most of the changes made
to fat and vfat since 2.6.8.1 and I wasn't able to see anything
there that looked like it would help your cause.
