            Bug ID: 203321
           Summary: Kernel Panic when i restart host
           Product: Virtualization
           Version: unspecified
    Kernel Version: 4.19.x - 5.0.7
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: kvm
          Assignee: virtualization_kvm@kernel-bugs.osdl.org

        Regression: No

Hello,

I have a problem with my Linux. When i use Qemu/KVM with libvirt, the GPU used
by the Guest is automatically bind to VFIO when i launch the VM and unbind when
the VM is closed.

The issue is that I have a kernel panic each time i reboot/halt the host after
to use the VM. The only solution that i found is to set "amdgpu.dc=0" in the
GRUB command line. But with this solution, FreeSync and HDMI sound is disabled.

I would like to know if there is an other solution to avoid this kernel panic
and this workaround ?

Kernel Panix

Hello Alex,

Sorry for the delay. I attach a photo take with my smartphone. I don't know
where i can find a log from a kernel panic after reboot.
