I've had an issue with the exact same symptoms, only there was no Thunderbolt involved. In my case it was a bad PCIe-sata controller that I tried passing-trough. It was a $13 ASM1062 that I bought from China, when replaced with a $39 ASM1062 the problem went away. The failing setup worked flawlessly in both Linux and Windows as long as I did not do virtualisation. The only visible difference between the two ASM1062 was the PCB-layout, and that the failing one had "classical" capacitors while the working one had only SMD-components in addition to the controller-chip and sata-sockets. Hope this info helps. -Hagbard Celine _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
