Can't remove directory from NCP server

[AZLinux]

Client side:
Ubuntu 12.04
ncpfs 2.2.6-8

Server side:
Novell OES2

1. Mount a Novell Netware volume with ncpmount command:
/usr/bin/ncpmount -S 172.16.1.X -A 172.16.1.X -U .user.au.ou -V volumename -y utf8 -p cp850 -m -d 0755 -f 0644 /folder1/folder2 -u user -g users -N nfs -o tcp

2. Create a new directory (folder3)
mkdir /folder1/folder2/folder3

3. Remove folder
rm -rf /folder1/folder2/folder3

4. Error message
Device or resource busy
---------

However, removing files (not directories) , it does not exist any problem

Same problem here.

Ubuntu 12.10
ncpfs 2.2.6

Status changed to 'Confirmed' because the bug affects multiple users.

Can someone with access to a netware server please check if this is still an issue with the below kernel? I think I narrowed it down to the root cause, but I can't be certain since I don't have a netware server.

Hello Dave

I'll try again this morning

Hello Dave

We have tested the new kernel, that you attach, and behavior is similar when try to remove a NCP Network folder

Error: Device or resource busy

Dave, we have Netware servers and we are available to perform further tests

I bisected this issue down to commit 1d2ef5901483004d74947bbf78d5146c24038fe7 when building a kernel for lucid.

If I build 003f6c9df54970d8b19578d195b3e2b398cdbde2 using mainline-build-one for lucid which is the commit immediately prior to 1d2ef5901483004d74947bbf78d5146c24038fe7 the resulting kernel works fine on lucid. However if I build the same commit using mainline-build-one 003f6c9df54970d8b19578d195b3e2b398cdbde2 precise rmdir works fine, but rm -rf does not on precise.
