When does the lockup occur? When mounting? Later? What is the command that
triggers it?

Could you edit fs/ntfs/Makefile and remove the hash in front of the -DDEBUG
in the EXTRA_CFLAGS line? Then recompile, insert the module and as root issue:

echo -1 > /proc/sys/fs/ntfs-debug

This will activate extensive logging in NTFS. If you now can reproduce the
hang and send me the syslog output (which hopefully will be captured) I
should be able to figgure out where and why it crashes.

Thanks in advance,
