Created attachment 136447 [details] kern.log 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.
Created attachment 136448 [details] 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.

I blacklist it now for efficiency and smaller dmesg. 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.
