Fixed in trunk and 09r1.
As so far, SMP still not support tickless.

SMP kernel seems workable when enabled NO_HZ and TICKSOURCE_GPTMR0
root:/> zcat /proc/config.gz | grep TICKSOURCE_GPT
CONFIG_TICKSOURCE_GPTMR0=y
root:/> zcat /proc/config.gz | grep NO_HZ
CONFIG_NO_HZ=y
root:/> zcat /proc/config.gz | grep SMP
CONFIG_SMP=y
root:/>
Close this bug.

Trunk is OK, now I'm trying 09R1.

09R1 latest revison 7412 also works with SMP + NO_HZ when TICKSOURCE_GPTMR0 and
TICKSOURCE_CORETMR.
