Sorry David.
That is not an option. It's a production server on 2.6 kernel. 4.0
kernel is not in Base repos and I don't know which impact installing the
newer kernel version will have on this server. Any other options?
You could backport the patch to the version you have.

What OS is this?  Is it RHEL/CentOS?  If so, halt_poll_ns will be in 6.7
which will be out in a few days/weeks.

Paolo
OK. As said CentOS 6.6.
But where do I put this parameter?
Regards, Hansa
