Yes, I missed ahci.ko module on my PXE server in amd64/8 tree :-/ [kernel reinstall] Well, ahci problem solved, but I still have much worse performance (and different on ada0 and ada1!): ada0, MC 50-60 MBps ada1, MC 13-25 MBps ada*, 5017 130+ MBps Could you please post SATA/AHCI BIOS settings from your machines?
