Junk Suresh,

I think the problem is that the file has too many GCPs to
be written to the tag in the GeoTIFF file.  One possible
solution is to rectify the image with gdalwarp before
writing to GeoTIFF.   But you can also feel free to file
this as a bug.  I ought to do something about it.

Best regards,
