Did you make sure the bd_info structure matches?

Did you make sure that "clocks_in_mhz" is not set?

This is a completely wrong cocnlusion.

This is already reason to suspect you are passing bad  parameters  to
Linux, i. e. you have a bd_info mismatch.

If your ramdisk is really bigger than 4 MB, pass a ramdisk= parameter
to the kernel; otherwise (and this is my guess) you are  passing  bad
params,  probably  because  you  are  using a non-matching version of
bd_info.
