T4240RDB SDK 2.0 Kernel crashes

Hi,

We have a T4240RDB board. Currently there is a QorIQ SDK v1.5 U-Boot, fman-ucode and kernel V3.12(SDK 1.7) installed. We want to upgrade the linux to 4.1 of the SDK 2.0. However when using SDK 2.0 linux, we observe a crash

 

kernel BUG at /media/nslab12/work2/Yocto/QorIQ-SDK-V2.0-20160527-yocto/build_t4240rdb/tmp/work-shared/t4240rdb/kernel-source/drivers/staging/fsl_qbman/qman_config.c:521!

 

Hence , understanding that SDK 2.0 requires fman-ucode 106.4.18 for correct functioning, we tried to install the fman ucode 106.4.18 of the SDK 2.0 package.  That led us to the problem as given in 

T4240: Cannot change to alternative flash boot section  (due to the flash map change between SDK V1.5 and SDK V2.0)

 

In order to quicky verify if upgrading fman ucode to 106.4.18 will solve the crash, I flashed the fman ucode to the fman ucode address as in SDK V1.5 FLASH MAP ( EFF40000)

Now we see that the new fman ucode is loaded. However the crash is still seen.

Can you please help me solving the crash?  Please provide me some directions.

The Kernel crash :
