Could you do the following inside the configured kernel source directory
corresponding to the compiled kernel that produced this oops:

make fs/ntfs/attrib.s

And then please email me the file fs/ntfs/attrib.s that is generated by
the above command. I need this to find out at which place in the code
the oops actually happened...

Also could you tell me which Windows version the ntfs partition was
created with and which windows version last accessed the files?

Finally is this bug reproducible when you access a particular file or is
it a once off event? If a particular file, then would you mind running
a utility that I can email you (source or binary or both whichever you
prefer) so I can capture the metadata for the inode of the file?

Thanks a lot in advance.

Best regards,

Anton
