ata, UDMA66 and UDMA33

["Ayrton Senna"]

Hi.

  I'm getting more confirmations that ATAng works strange when cable, motherboard and device supports different modes. I was told (no logs) that when using DPTA hdd (UDMA33) with UDMA100 motherboard, ATAng ends up with quite weird results, like resetting hdd and "Device disappeared" error message after that.
  Besides, I still can't boot with ata.ata_dma=1...

Good luck!
