Hi,
This patchset introduces cpuidle infrastructure to POWER, prototyping
for pSeries, and also does a major refactoring of current x86 idle
power management and a cleanup of cpuidle infrastructure.

Sorry, but it seems that the patch did already do the work. The other
problems were hardware problems and are not related to this patch (it
even happened without applying it). So it seems that the skb leak may be
solved with the provided patch.
Kind regards,
