Boot freezes when X starts. The screen shows a garbage. Before it console show:
[...] desktop kernel: [ 14.060255] nouveau 0000:01:00.0: DRM: GPU lockup - switching to software fbcon
Same thing happens with 4.9, 4.13 and 4.14 kernel.
I used this card on motherboard with NForce2 chipset and it worked fine (with 4.9 kernel). Now i use P4i65GV with Intel 865GV chipset. I think there can be some drivers conflicts.
Boot with "nomodeset" option works.
https://bugs.freedesktop.org/show_bug.cgi?id=91037 is the similar (may be the same) problem.
Does nouveau.config=NvAGP=0 help?
I assume this is an AGP device?
Yes, it works. Thank you!
Yes, it's an AGP device.
A few things:
(a) The messages in your dmesg are very confusing. They talk about a 4M AGP aperture, but then 128MB GTT?
(b) You appear to have the onboard video enabled. I don't know about i865, but at least some chipsets were unable to both do AGP *and* use onboard video.
(c) Try enabling AGP by forcing a specific mode. e.g. nouveau.config=NvAGP=2 will force AGP 2x.

dmesg (linux-4.9, modprobe.blacklist=i915, nouveau.config=NvAGP=0)
(a) 128MB is default memory that assigned to onboard video. It's not the AGP.
(b) Yes, i had onboard card enabled (Intel Extreme Graphics 2, i915). But that wasn't the problem: i try to blacklist the driver and boot still freezed. I blacklist it now for efficiency and smaller dmesg.
(c) nouveau.config=NvAGP=2 doesn't work: same thing.

Well, just because you don't load the driver doesn't make it disabled. It'd be something in the BIOS.
The BIOS let me choose a priority of the graphic devices (AGI is first, than PCI, than onboard). I didn't find option to disable the onboard video. So, it may be it. Or not. I don't know how to check.
And i try the values from 3 to 7 with the NvAGP option. It didn't work.
