Package: linux-2.6
Version: 2.6.32-29bugfix1
Severity: important

Hi,

I encountered the following issue on my *own build* of
2.6.32-5-openvz-amd64 (2.6.32-29);  having applied a very small patch to
IPv6 netfilter (Bug#607041) which I'm fairly confident didn't cause
this.  I'll try to reproduce this on an official build of 2.6.32-29 when
I have the opportunity.

I previously had /var/lib/tftpboot exported to three hosts, using
nfs-kernel-server on the OpenVZ hardware node (this was not inside of an
OpenVZ container).  I bind-mounted a different directory onto that path,
added another export of that path to a new host, and ran 'exportfs -ra'.
 Sort of like this:

< /var/lib/tftpboot exported to three hosts already >
$ mount --bind /home/whatever /var/lib/tftpboot
$ vi /etc/exports
< added an export of /var/lib/tftpboot to another host >
$ exportfs -ra

When I then tried mounting it from a remote machine I noticed the oops
on the nfs server.  So I don't know if it was triggered by the 'exportfs
-ra' itself, or upon the next mount after that.

The underlying filesystems are reiserfs.

After the oops, I seem to be unable to mount these nfs exports from
remote systems (so nfsd basically stopped working) :

Version: 2.6.32-31

I think I can also call this one fixed, as I've not seen this issue for
a long time;  OpenVZ feoktistov (in linux-2.6 2.6.32-31) was probably
the specific version that fixed it since it contained many NFS fixes.

Thanks!
