    Thanks Jake,
    I don't quite understand what mvrk was doing, and unsure if putting those exact entrees is appropriate for my motherboard and AMD cards. Is it a general solution or I need to find the specific addresses to my AMD cards?

    Will definately give your solution a good read!

    I was experiencing the same issue with a GTX 980, and apparently what mvrk suggests almost worked for me: changing "bridge" to "link" fixed the freeze, but then the VM wouldn't boot anymore after the first time, until I rebooted the host (the VM logs mention a panic). Changing it to "d3d0" seems to work: still no freezes, and I can power off and on the Windows VM at will.
    If you try this, make sure to reboot the host after changing /etc/vmware/passthru.map.

    Thanks a lot for this thread.

    1002 ffff link false to /etc/vmware/passthru.map?

    i have a gtx 1070 and gtx 1050 ti passthrough to 2 different vm's in esxi 6.5 with no major issues. the only config change made was to hide the hypervisor from nvidia drivers. originally tried passthrough with a radeon pro wx 4100 but that had major problems with freezing the entire esxi host on vm reboots.

    on another note, i also had these freezing issues when passing through a usb 3.0 card that used a fresco logic controller. issues went away after switching to a asmedia controller.

    having a intel ssd 750 nvme passthrough to the vm along with the nvidia gpu and usb 3.0 also caused stability issues in the vm (nvidia driver crashes) so i just don't have the ssd passthrough and it's been stable since.

    still present in 6.5 u3. This worked great to get my vid cards and USB going, but it still locks up whenever i try to passthrough my LSI2008 controller. I tried the "d3d0" and "link" settings but it PSODs on them both when shutting down a vm.
