Hello, Jean & 0602.
I was digging ICH docs to reimplement ata_piix initialization and found
out that 6300ESB lists high bits (the present bits) of PCS register as
reserved. But they indiciate that the bits might change anytime just as
in other docs. I think something went wrong with those bits in that
particular chipset and Intel decided to ignore the bits.
I'm wondering whether your problems are related to this. Can you guys
please run 'lspci -n' on your machines which had the piix initialization
trouble and report the result here?
Note that we still get the PCS bits wrong because, e.g. they only apply
to ports 0 and 2 on some chipsets, not ports 0 and 1 like you would expect.
