Hey guys, I have a windows 10 vm with a passthrough VGA (NVIDIA Corporation GM204 [GeForce GTX 970]) and a passthrough USB Controller (Intel Corporation C600/X79 series chipset USB2 Enhanced Host Controller #1). It uses the virtual Q35 chipsetand and is configured using virt-manager. On the host I use Debian unstable with a Advanced Micro Devices, Inc. [AMD/ATI] Curacao XT [Radeon R7 370 / R9 270X/370 OEM] VGA with radeon driver. If I shutdown the VM (or reboot), the host freezes when the VM should stop. There are also some random host freezes when the guest runs for many hours. I already had this problem when I was using KUbuntu 15.10 and Debian Stable (fglrx for host VGA and i440FX virtual chipset). I'd like to know which package I should file the bug against. There are no special syslog messages when the host freezes. I only find the following messages spammed into the syslog while the guest runs on the Debian unstable host (0000:01:00:0 is the AMD Radeon Host VGA): Aug 19 16:04:04 fp-pc kernel: [ 6280.647496] VM
