no, what i meant is, if:
#
# Processor type and features
#
CONFIG_NO_HZ=y
CONFIG_HIGH_RES_TIMERS=y
than try setting acpi like:
#
# ACPI (Advanced Configuration and Power Interface) Support
#
CONFIG_ACPI=y
# CONFIG_ACPI_SLEEP is not set
# CONFIG_ACPI_PROCFS is not set
# CONFIG_ACPI_AC is not set
# CONFIG_ACPI_BATTERY is not set
# CONFIG_ACPI_BUTTON is not set
# CONFIG_ACPI_FAN is not set
# CONFIG_ACPI_DOCK is not set
# CONFIG_ACPI_PROCESSOR is not set
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_IBM is not set
# CONFIG_ACPI_TOSHIBA is not set
# CONFIG_ACPI_CUSTOM_DSDT is not set
switching on the acpi in general, but switching off the other acpi stuff
like fan, button etc. resolved some issues here.
read here:

"NOTE: Since rt patch 2.6.18-rt6 you will probably have to activate ACPI
option to activate high resolution timer. Since the TSC timer on PC
platforms, as used in the previous versions, are now marked as
unsuitable for hrt mode due to many lacks of functionalities and
reliabilties, you will need i.E. pm_timer as provided by ACPI to use as
clock source. To activate the pm_timer, you can just activate the
ACPI_SUPPORT in menuconfig and deactivate all other sub modules like
"fan", "processor" or "button". "
that helped here!
cheers,
