I get this error "Looks like our kernel doesn't have the support for KIST anymore." on my relay

Im running a tor relay, running tor-0.3.2.3-alpha and I keep getting this error. [notice] Looks like our kernel doesn't have the support for KIST anymore. We will fallback to the naive approach. Remove KIST from the Schedulers list to disable.

Relay kernel, GNU/Linux 2.6.32-042stab111.12 x86_64
