Hi,

I'd like to confirm that this issue still exists with 2.6.30.

For a while my server has been running fine after the upgrade to 2.6.30.
My NFS/diskless desktop worked just fine. Then yesterday evening suddenly the
first "reconnect_path: npd != pd" messages popped up. Sometime during the
night the frequency of those messages showing up increased to > 100 msgs/sec
in average.

On my desktop I got a few 'stale NFS handles'. The most prominent one
being '/etc'. Needless to say, NFS is completely useless for me right now.
The desktop has been running various 2.6.30-rc kernels and is now also on
2.6.30 vanilla.

The messages started to show up when I upgraded the server from 2.6.25 to
2.6.29 (and now to .30).

The underlaying filesystem on the server is XFS (sata/raid6/lvm/xfs).
This is an x86_64 kernel.

I've ported my .config forward manually using 'make oldconfig' by saying 'yes'
to options that seemed reasonable to me.

As reported on the other thread regarding NFS + XFS, I did not experience any
kernel crashes with 2.6.30 anymore.

My .config is attached.

Any further info I can provide ?

Cheers,

Mathias

More or less the same here. My client machine (2.6.30) however worked just
for a few hours. It does however work fine using the older Kernel (2.6.27.x)
on the Server.

This is also XFS+NFS here. I will also attach the associated .config of the
Kernel.

Regards

Sven

Hi, I want to confirm that I'm still having this problem in 2.6.30. I'm
using Debian (unstable) too, and the exported fs is XFS.

Here is a related bug report:
