I was willing to test the kernel when it's enabled, but the kernel did
cause an issue on my machine already when it was disabled.
Here is what I get
uname -a
Linux box 3.10.9-rt5 #1 SMP PREEMPT RT Fri Aug 23 11:14:14 CEST 2013
i686 GNU/Linux
zgrep _HZ /proc/config.gz
CONFIG_HZ_PERIODIC=y
# CONFIG_NO_HZ_IDLE is not set
# CONFIG_NO_HZ is not set
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000
This is plain vanila +rt patch.
