This has been solved. It was “hardware” related, sort of. I had turned of the EIDE board via setenv pcib-probe-list figuring that I was not using it and did not need it. (I also turned off the mach64 video card). Well curiously I think that prevents the system from being able to use DMA (I assume the IRQ never get allocated or something like that). Which causes these cards to be forced into PIO4 and not really work correctly with modern kernels.
