Hello,

I tried clearing all BIOS settings to standard. So s-ata controller does 
p-ata emulation legacy. It seems to use ata_piix. Some errors occurs in 
dmesg, see bellow. But everything seems to work fine with it. No ext3 
issues. On the other hand, the I/O is very low (4.2 MB/s) in comparison 
to ahci. Maybe this can give us a hint for problems in ahci and 64-bit dma.

Cheers,
Marco
