[issue1872] nfs stall (fix pushed)

I have update to latest master / 2.6:
I still see nfs stall, but not so often,
now with message below on console.

Is NFS supposed to recover from this?

I use default values for these sysctls (2M, 64),
which values could be a applicable?

As all systems have plenty RAM (2GB) for the use,
it would be nice if values were auto tuned so this didn't happen.

I have foced core dump, please say if I should upload it.

- console
Warning: NFS: Insufficient sendspace (2123008):
