[U-Boot-Users] Ramdisk: Bad Data CRC

Please help.  I am trying to boot my system using a
fairly large ramdisk (~24MB uncompressed, ~8MB
compressed).  I can tftp it up to my board fine, and
can run imi, and it says the checksum is ok, but
whenever I try to boot I get the following error:

 => tftp 400000 uRamdisk
Speed: 100, full duplex

Is it too large of a ramdisk?  If so, what is the
maximum size allowed.  I have 256MB of DDR SDRAM. This
is a custom MPC8540 sytem.

Thanks,
   Jeff Stevens
