Re: [Linux-NTFS-Dev] ntfs OOPS (2.5.63)

[Anton Altaparmakov]

Hi Randy,

Could you try to turn on debugging in the NTFS driver (compile option in
the menus), then once ntfs module is loaded (or otherwise anytime) as root
do:

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

Then mount and to the directory changes. Assuming that you get the bug
again could you send me the captured kernel log output? (Note there will
be massive amounts of output.)

The code looks ok and I can't reproduce here so it would be helpful to see
if there are any oddities on your partition. Just to make sure it is not
the compiler, could you do a "make fs/ntfs/inode.S" and send me that as
well?

Thanks,

	Anton
