kernel panic booting uimage-2.6.29-r44-beagleboard.bin on revC3

Hi,

I am trying to boot uImage-2.6.29-r44-beagleboard.bin from an angstrom
demo distribution. After loading the kernel image into memory from my
SD card and running bootm, I get a kernel panic - the trace looks like
this

mount_block_root
mount_root
prepare_namespace
kernel_init

kernel panic - fatal exception in interrupt

any ideas to resolve this would be very helpful

thanks for your time
