After more experiments:
1) A pair of any disks are ok as ad0 and ad1, both in dma mode.
2) In a pair ad0+ad2, disk ad2 (irrespective of disk make)
is not mounted in dma that easy. BUT, if I wait long enough,
(about 1 min) it says:
"ata1: trying to fallback to PIO mode"
after which I have ad0 in dma, ad2 in pio, and no further problems.
Very clever behavior in such a case!
Thanks a lot for your response.
Do you know a way to say that I want just PIO for disk ad2?
