l4android can not run rightly on Pandaboard?

[longjks]

hi,
I am working to make Android4.0.4 boot on PandaBoard. However the l4android stop unexpected.
I can see some page-fault error in the android_term, but I can not save it from android_term.
!WARN: rild: Page-fault above task size: pfa=ffff00c0 pc=b7b02758
!0:ffff00b4 00000005 00000000 ffff00b4 4:b7b2e004 00000005 00000004 0000ab1c

!CPSR:40000130 Err:0041000f
What does this error mean?

How to decide which thread is waiting for the pager of the system? Do you have some help doc for debugging？ 


By the way, You can see my log in attachment.

thanks.
