Hi,
I have problems with my system when I want use intel I/O virtualization. I get black screen and information in logs like :

DRHD: handling fault status reg 3
DMAR:[DMA Read] Request device [01:00.0] fault addr 19e3b9000
DMAR:[fault reason 02] Present bit in context entry is clear
NVRM: Xid (0000:01:00): 57, Failed shmoo sddr3 link training
DRHD: handling fault status reg 3
DMAR:[DMA Read] Request device [01:00.0] fault addr 195672000
DMAR:[fault reason 02] Present bit in context entry is clear
NVRM: Xid (0000:01:00): 56, CMDre 00000000 00000000 00000000 00000001 00000001


Without Iommu all is ok. Option intel_iommu=igfx_off deosn't help.
I made tests with kernel older than 3.1 and all was ok. So it occur only on kernel >= 3.2.
You can find more in attachement.

best regards,

Having the exact same problem with a GT520 and 9500GT using kernel 3.3.7 and driver version 295.53.
Same problem with 302.11-1 Beta. Tested under archlinux and fedora 17.
