I had similar problem with some CF cards (while other like in your 
case worked fine).

Try disabling probing of the slave ide0 interface (hdb). I'm not 
familiar with MPC5xxx, but most likely you can modify mpc5xxx_ide or 
whatever code sets up access to your CF card.

Find where an instance of ide_hwif_t is initialized for ide0 and add 
something like:

	/* Don't probe second drive */
        hwif->drives[1].noprobe = 1;

Thank you.  It was indeed the probing for the second drive that was=20
causing the problem.
Adding hdb=3Dnoprobe to the kernel command line (bootargs) fixes the proble=
m=20
without kernel modifications.

Thanks again,
