Lab tested well and we pretty rapidly found the problems with non Intel AHCI that had 4GB cases. > 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. 4.2MB/sec is abnormally low. > scsi0 : ata_piix > scsi1 : ata_piix > ata1: SATA max UDMA/133 cmd 0x0000000000011cc0 ctl 0x0000000000011cb6 > bmdma 0x0000000000011c60 irq 22 > ata2: SATA max UDMA/133 cmd 0x0000000000011cb8 ctl 0x0000000000011cb2 > bmdma 0x0000000000011c68 irq 22 No devices.
