On OMAP 5912 OSK I get:

my config:

CONFIG_GENERIC_TIME=y
CONFIG_GENERIC_CLOCKEVENTS=y
# CONFIG_OMAP_MPU_TIMER is not set
CONFIG_OMAP_32K_TIMER=y
CONFIG_OMAP_32K_TIMER_HZ=128
# CONFIG_OMAP_DM_TIMER is not set

#
# Kernel Features
#
CONFIG_TICK_ONESHOT=y
CONFIG_NO_HZ=y
CONFIG_HIGH_RES_TIMERS=y
CONFIG_PREEMPT=y
CONFIG_HZ=128

As the "ok" in "CPU: Testing write buffer coherency: ok" is already 
missing in your output, maybe it is anything else?
