Hello,

for some reason my hardware (Fabiatech FX5621) doesn't work with FreeBSD 10.1 while it works perfectly with version 8.3. I tried to boot from a USB drive, disabling from BIOS all IDE drives and using all hints commands I found with no luck! This is what I tried:

    set hint.atapci.1.msi=0
    set hint.atapci.0.msi=0
    set hint.ata.1.mode="PIO4"
    set hint.ata.0.mode="PIO4"
    set hint.acpi.0.disabled=1
    set kern.cam.ada.write_cache=0


The boot loops with this error:

    (aprobe0:ata1:0:1:0): ATA_IDENTIFY. ACB: ec 00 00 00 00 40 00 00 00 00 00 00

I found some FreeBSD users with similar errors:

Do you have any suggestions?
