Unless you have a support contract with some vendor, nobody will look at
bugs from such an old kernel.  There are a hundred old bugs that might
have been fixed already.

This is likely a hardware error.  Probably due to the fact that ext3
is not a good filesystem to use on CF because the journal is always
overwriting the same part of the CF device.  Try something like JFFS2
