>Description:
HI ,

   We are upgrading NetBSD 5.1 kernel to 7.1.2 kernel for XLP308L Processor. During up-gradation we are facing a system hang in kernel bootup stage.

Control is not transferring  to mach_init function (usr/src/sys/arch/evbmips/rmixl/machdep.c) system got hung in locore.S ( usr/src/sys/arch/mips/mips/locore.S)

Since console driver is not initialized we could not able to see the prints.  

It would be great help if could able to share some debug points.

      
Note:- 
       We have build new tool chain for 7.1.2 kernel.
       we are using uboot version  U-Boot 2010.03-rc1

Thanks and Regards,
Karthik.G
