[LinuxBIOS] slow X startup on m57sli-s4

[Ward Vandewege]

Hi all,

My test machine has an Nvidia plugin card that I'm using with the free
software nv driver.

I've attached a diff between the Xorg.0.log file booted into the proprietary
BIOS, and into LinuxBIOS (Xorg.diff). These are the most interesting bits
(lines starting with + are LinuxBIOS):

  GeForce Go 7900 GTX, Quadro FX 2500M, Quadro FX 1500M, GeForce 6150,
  GeForce 6150 LE, GeForce 6100, GeForce Go 6150, GeForce Go 6100
 (II) Primary Device is: PCI 02:00:0
+(WW) NV: No matching Device section for instance (BusID PCI:0:1:3) found
 (--) Chipset Unknown NVIDIA chip found
 (II) resource ranges after xf86ClaimFixedResources() call:

This PCI:0:1:3 device is new. It didn't exist under the proprietary BIOS, and
is identified as such by lspci:

  0000:00:01.3 Co-processor: nVidia Corporation: Unknown device 036b (rev a2)

and lspci -n

  0000:00:01.3 0b40: 10de:036b (rev a2)

What is this thing? A co-processor?

The other interesting difference is:

 (II) Reloading /usr/lib/xorg/modules/libint10.so
 (II) NV(0): Initializing int10
-(II) NV(0): Primary V_BIOS segment is: 0xc000
+(EE) NV(0): V_BIOS address 0x420 out of range
 (--) NV(0): Chipset: "Unknown NVIDIA chipset"
 (**) NV(0): Depth 24, (--) framebuffer bpp 32

Not sure if it is related, but there is a 30+ second delay in the X startup
at this point:

(II) Loading sub module "ddc"
(II) LoadModule: "ddc"
(II) Reloading /usr/lib/xorg/modules/libddc.so
(II) NV(0): I2C bus "DDC" initialized.
(II) NV(0): Probing for analog device on output A...
(--) NV(0):   ...can't find one
(II) NV(0): Probing for analog device on output B...
(--) NV(0):   ...can't find one
(II) NV(0): Probing for EDID on I2C bus A...
(II) NV(0): I2C device "DDC:ddc2" registered at address 0xA0.

...... very long delay .......

(II) NV(0): I2C device "DDC:ddc2" removed.
(--) NV(0): DDC detected a DFP:
(II) NV(0): Manufacturer: SAM  Model: 1ae  Serial#: 1112683056

Any ideas as to what's going on here?

Hints greatly appreciated, as always.

Thanks,
Ward.
