These errors crop up quite often.  They indicate that either the drive 
isn't working according to spec or else the UHCI controller is 
out-of-spec.  Hard to say which, but it doesn't much matter...

I'll try to get hold of the changes to the EHCI driver introduced in the
-mm release.  Or Eero, since you already have both the vanilla -rc4 and
-mm kernels, you could find the differences yourself.  The files of
interest are driver/usb/host/ehci*.[ch] -- and if you feel like
experimenting you can simply take the -mm versions of the those files, put
them into the -rc4 source directory, and see what happens when you build
and run them!
