This is wrong, normally, you should have something like:
[ 0.000000] OMAP clockevent source: GPTIMER2 at 13000000 Hz
[ 0.000000] OMAP clocksource: GPTIMER3 at 13000000 Hz
[ 0.000000] I-pipe, 13.000 MHz clocksource
This is ensured by this piece of code in arch/arm/mach-omap2/timer.c:
#ifndef CONFIG_IPIPE
OMAP_SYS_TIMER_INIT(3, 1, OMAP3_CLKEV_SOURCE, 2, OMAP3_MPU_SOURCE)
#else
OMAP_SYS_TIMER_INIT(3, 2, OMAP3_CLKEV_SOURCE, 3, OMAP3_MPU_SOURCE)
#endif
So, my guess is that you have some other patch changing this.
