Hello,

I want to report to you a really big bug.

vfio passthrough dont works with Sata controler (an AsMedia 1061) ! When i
try to use vfio with this controler it work only once.

When i use vfio for VGA i can reboot (or shutdown and start again) my VM
with out problem, but for any other PCI card the VM refuse to reboot.

In dmesg i have this error :

[  404.206866] dmar: DRHD: handling fault status reg 2
[  404.206870] dmar: DMAR:[DMA Write] Request device [07:00.0] fault addr
2affdf000
[  404.206870] DMAR:[fault reason 05] PTE Write access is not set
[  404.206877] dmar: DRHD: handling fault status reg 2
[  404.206879] dmar: DMAR:[DMA Read] Request device [07:00.0] fault addr
2affda000
[  404.206879] DMAR:[fault reason 06] PTE Read access is not set

Thanks.
