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.
