I am trying to boot my board with imx35 3 stack board with linux 2.6.31(source available in freescale SDK). I could find that during booting the kernel gets crashed from init/main.c/rest_init() function.
I have done some analysis in rest_init() function and found that kernel crash occurs when it tries to schedule the process kthreadd invoked from the rest_init() function.
The crash log is given below –
Unhandled fault: imprecise external abort (0xc06) at 0x00000000
