MPC5121 new board constantly resetting after u-boot passes control to Linux

Dear all,
We are attempting to bring up a new MPC5121e board, somewhat based on the
Silicon Turnkey's ADS5121 development board. We are using a kernel and
u-boot based on Freescale/STx's board support package.
We have successfully modified u-boot for the 64MB of DDR2 RAM, and we can
use u-boot's (and the BDI's) memory test facility to check that the RAM is
working.
Our problem is that as soon as control is passed from u-boot to Linux, the
board immediately resets. It appears that the kernel has been decompressed
correctly, and the memory at 0x00000000 appears to be similar to the same
memory on the ADS board at the same address. i.e. We have some confidence
that the kernel is being decompressed correctly.
With debug on, u-boot produces the following output on the console:

At this point, the board immediately resets. There is no hint of life from
the kernel from the console, although setting a breakpoint on the BDI at
0x0000000 and tracing through appears as though some code (although we don't
know what) is being executed.

the reboot on the BDI), we would be extremely grateful for the help.
