    I've had the IOMMU option enabled since it became available (F4a), and there was no negative impact on normal operation. IOMMU passthrough itself is a different story, of course. This also applies to the F4 BIOS. Your problem could also be related to other factors, for example an attached USB mass storage device, or BIOS misconfiguration as pointed out above. The 890FXA BIOS sometimes stalls if it can't detect a proper filesystem on a USB disk. I haven't found out yet how to disable this. Gave me a few headaches before I noticed I left my USB pen drive plugged in and it wouldn't boot because of that. :)

    Hi,
    thanks for your answers. Should I try to flash via DOS? (I flashed first time via Q-Update)
    I'll try the tipp with the usb devices.

    What I already tested is, that I set in BIOS "fail-save defaults" and changed only IOMMU to enabled. This also didn't worked and gave me the results of my previous post. (Mainboard boots, hangs after initialize of HDDs and ROMs)

    It should not be neccesary to flash again if you had a successful flash.
    fail-save defaults?
    Load Optimized Defaults save y and exit. Then set your memory voltage to manufacturers specifications, Set the Integrated Peripherals SATA controllers to where you had them set before you flashed. IDE, AHCI,RAID. To make the correct changes it is important to know what type or how many hard drives you are using. Where you have the drives plugged in, and which mode your OS is setup to. IDE, RAID, or AHCI. Also another thing try to disable floppy drive support where it says "1.44M, 3.5" to None in Standard CMOS Features.

    Hi.

    I've loaded Load Optimized Defaults and it also didn't worked. Still the same problem with IOMMU. Floppy is disabled, as I don't have any more one. Only USB-Floppy.

    Any Ideas?

    Does ANYBODY have working IOMMU with Linux and KVM?

    I'm planning on buying a GA-890FX-UD5 today for this very reason and all I'm seeing is that with IOMMU switched on you can't even boot!?

    And another guy saying he's given up with KVM and is using PV over XEN.

    The boot issues described here are most likely unrelated. I can assure you that turning on IOMMU in the BIOS does not affect normal operation, neither on Windows nor on Linux.
    It seems there are some issues with KVM, but others have confirmed that xen works fine. If you check the post of trikolon further up, you'll see he has successfully passed a network card through to the VM.

    Also, thanks for the hint about disabling USB mass storage support. My boot time increased quite a bit. :)

    Well my boot problem must depend on IOMMU, as with enabled IOMMU-option in bios I can't even boot from cd/dvd nor hdd. It just get not so far. That the problem :( I've still no fix.

    You might have already tried that, but did you reflash your BIOS with the current stable Version (F4)? Did you reset all BIOS settings, checked if booting worked as-is, enabled just the IOMMU setting and checked again?
    I'm not considering you incompetent, but judging from my own experience and the success of others here, I find it hard to believe your boot problem is purely related to IOMMU.
    Could it be your hardware? What board revision do you have, what PCI(e) cards are installed, what HDDs/SSDs/Optical drives are attached?

    Hi :)
    Yeah, I've tried several times to flash the current stable F4-version. I've always reset all settings to default and only enabled IOMMU as new option. This hasn't worked too :(

    My board revision it 2.0.

    My pcie-cards are:
    ASUS P1 Physx PCIe
    Creative Sound Blaster X-Fi PCIe
    Sapphire Vapor-X 4890 2GB PCIe

    My drives:
    1x WD Raptor 600GB SATA3-version
    5x WD Black 1000GB SATA3-version
    1x Plextor PX-880SA
    1x Plextor PX-B940SA

    I tried to remove ALL drives expect one hdd or one dvd-rom and the video card.
    In this combination its still not working. After initializing the drives from bios, i see only in the left corner an blinking cursor. The message with "loading operation system" (which comes from the bios!) is missing and system hangs..

    I am just out of my all ideas :(
