[BUG] nvidia-290.03 doesn't like IOMMU/DMAR features
1 Attachment(s)

I've a brand new Dell M6600 with a Quadro 4000M in it; X hangs during startup and the X driver
complains with the following:
[ 615.863] (EE) NVIDIA(0): EVO Push buffer channel allocation failed
[ 615.863] (EE) NVIDIA(0): *** Aborting ***
[ 615.863] (EE) NVIDIA(0): Failed to allocate EVO DMA push buffer
[ 615.863] (EE) NVIDIA(0): *** Aborting ***

I "fixed" it by disabling all IOMMU/DMAR and INTR_REMAP features in the kernel.
Please have a look at this, as I'd like to make use of the VT features.
Attached a bug report in the non-working case.
