I am not sure, never having played with a mcd0 type drive :-(.

Please try this and let us know if that fixed the problem.  If you can make
the problem go away with say a value of 15000000 (ie, 10x what it is now)
please do a binary search for the value that just makes it work and send
that to us.

I'd rather not, we want to eliminate config and kernel options like this,
not make more of them.
