It points me directly at the code responsible for the hangs. The above should hopefully allow me to reproduce the hang and fix the problem. Most likely it is something to do with the dcache code in fs/ntfs/namei.c::ntfs_lookup() that handles the case insensitive file and directory names in NTFS. This is supported by the reported trace from the kernel showing that the code hangs inside ntfs_lookup() when the inode lock is attempted to be acquired. When I have a little spare time I will work on tracing and fixing the problem if someone doesn't beat me to it...
