Thanks for the additional dmesg daemonx.

I zeroed in on the
vgaarb: device changed decodes:
PCI:0000:01:00.0,olddecodes=io+mem,decodes=none:owns=io+mem
and looked at the git commit history of the VGA Arbitrator. It is
present in v2.6.32 and therefore it's presence isn't the cuplrit.
I note that the nvidia drivers helpfully tells us that
nvidia: probe of 0000:01:00.0 failed with error -1
-1 is symbolically known as -ENOPERM (see include/asm-generic/errno-
base.h) but in this case is not accurate. Looking at the nvidia kernel
interface source-code I see:
else
{
nv_check_pci_config_space(nv, FALSE);
if (rm_is_supported_device(sp, nv) != RM_OK)
{
nv_printf(NV_DBG_ERRORS,
"NVRM: The NVIDIA GPU %02x:%02x.%x (PCI ID: %04x:%04x)
installed\n"
"NVRM: in this system is not supported by the %s NVIDIA Linux\n"
"NVRM: graphics driver release. Please see 'Appendix A -\n"
"NVRM: Supported NVIDIA GPU Products' in this release's
README,\n"
"NVRM: available on the Linux graphics driver download page
at\n"
"NVRM: www.nvidia.com.\n",
nv->bus, nv->slot, PCI_FUNC(dev->devfn), nv->vendor_id,
nv->device_id,
NV_VERSION_STRING);
goto err_not_supported;
}
so the crux is at:
rm_is_supported_device(sp, nv) != RM_OK
which is an Nvidia Resource Manager function:
$ grep 'rm_is_supported_device' /proc/kallsyms
f9e6fc68 t rm_is_supported_device [nvidia]
which is contained in the binary blob 'nv-kernel.o' for which we don't
have source code.
grep -rn 'rm_is_supported_device' *
nv.c:4773: if (rm_is_supported_device(sp, nv) != RM_OK)
nv.h:618:BOOL NV_API_CALL rm_is_supported_device (nv_stack_t *,
nv_state_t *);
Binary file nv-kernel.o matches
So this is an Nvidia issue with how Resource Manager compares the NV
state pointer nvl->nv_state and the stack pointer sp.
