I have enclosed 4 files compressed with bzip2 documenting the
problem when an x64 client opens a file in a Samba share:

1. messages.x64.fmt.bz2   formatted full_audit log
2. pmn33.x64.bz2             formatted level 10 samba log
3. wireshark.out.bz2         formatted wireShark print-out
4. x64-26-07.bz2             capture file with relevant 200 packets

All files include data captured at 16:26:07 today.
The transaction opening the file for read, setting
kernel_flock and returning xattr should start at about
packet 69 in capture file.
