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. Here we see it correctly set up [ 14.063745] scsi host0: pata_pdc202xx_old [ 14.075370] scsi host1: pata_cmd64x [ 14.076299] scsi host2: pata_pdc202xx_old [ 14.076897] ata1: PATA max UDMA/100 cmd 0x1fe02000400 ctl 0x1fe02000408 bmdma 0x1fe02000440 irq 15 [ 14.076914] ata2: PATA max UDMA/100 cmd 0x1fe02000410 ctl 0x1fe02000418 bmdma 0x1fe02000448 irq 15 [ 14.087272] scsi host3: pata_cmd64x [ 14.088010] ata3: PATA max MWDMA2 cmd 0x1fe02c00000 ctl 0x1fe02c00008 bmdma 0x1fe02c00020 irq 13 [ 14.088026] ata4: PATA max MWDMA2 cmd 0x1fe02c00010 ctl 0x1fe02c00018 bmdma 0x1fe02c00028 irq 13 [ 14.090801] pata_cmd64x: active 10 recovery 10 setup 3.
