4 - FWIW I get that wait (WAIT (E, 0, 0x0887d, 0) ) when I activate the

6
7 # set "Bus options (PCI etc.)" -> "Support for DMA Remapping Devices"
8 to "*"
9 # set "Bus options (PCI etc.)" -> "Enable DMA Remapping Devices" to "*"
10 # set "Bus options (PCI etc.)" -> "PCI Stub driver" to "*"

12 Activating these options is prescribed by the KVM folks to allow VM
13 access of the GPM; <

16 - When I deactivate those options, the NV driver works fine. kernel:
17 linux-2.6.32-gentoo-r6 (and r3)

19 - Perhaps you could post these comments in the NV form. Perhaps you
20 could also advise them that they might get more participation if they
