Description Carlos Eduardo Monti 2004-05-19 19:32:38 UTC 
nvidia-kernel-5336-r3 and previous versions refuse to start (black screen, X uses 99% of cpu, checked through ssh session) with AGP enabled (Option "NvAGP" "2"), without AGP enabled (Option "NvAGP" "0" -- or 1, which since kt400 is not a supported chipset by nvidia's agp driver falls back to 0, or the "nv" driver from XFree86) the system works.

Tried it with the gentoo-dev-sources-2.6.5-r1 and development-sources-2.6.6.

Problem started after a system upgrade which included: new motherboard (Abit At7max2 kt400 chipset), Athlon XP2800+, 512mb of ddr ram.

The following shows up in the kernel log:

Please download http://dev.gentoo.org/~cyfred/nvidia-kernel-1.0.5336-r3.tar.bz2 and extract to your $PORTDIR_OVERLAY/media-video/ directory. Then try the ebuild provided in this tarball. 

It patches the kernel api driver so that proper kernel function calls are actually used not deprecated ones... I have notified nvidia of this will see what they say.
Comment 5 Carlos Eduardo Monti 2004-05-21 11:44:59 UTC 
Same result. (Badness in pci_find_subsys at drivers/pci/search.c:167)

From what I've seen in http://www.nvnews.net/vbulletin/forumdisplay.php?f=14 this is a symptom of an error, not the error itself. That function gets called trying to recover from an error and the causes could be many, mostly related to an unstable AGP bus. I've tried every BIOS setting related to AGP and nothing seemed to help.

I've also found out two new things:
1. When not using the vesafb driver instead of a black screen I get a screen with garbled ASCII characters.
2. lspci output for my video card shows the following line:
Latency: 248 (1250ns min, 250ns max)
Shouldn't the min latency be lower than the max? Other devices show that fine.
Comment 6 Andrew Bevitt 2004-05-22 20:20:26 UTC 
You know this _might_ be a rather big call but I _think_ the module is actually being de-prioritised by the kernel; Im trying to follow the scheduler code in the kernel but its hard without know exactly what the binary driver does...

Ultimately I think its a nvidia kernel api problem .. it looks like they use specific kernel calls that automatically get a higher (smaller interrupt) priority. But in doing so they effectively break the locking methods in the kernel on UP (single processor) machines. This problem is directly ported to SMP systems because the scheduling / locking routines ultimately are derived from SMP in the kernel.

Ultimately I dont think the kernel api was designed to work with a scheduler.

Please remember this ultimately is conjecture, and I could be wrong.

Why this only happens for some people is slightly more obscure, and I dont know the reason... 

Remember conjecture ...

Andrew, ask Seemant about some contact people at Nvidia. Maybe you can get in touch with people who could verify.
Comment 8 Seemant Kulleen (RETIRED) gentoo-dev 2004-05-28 14:40:34 UTC 
I've alerted Nvidia to this bug report, they'll be taking a look at it during this next week after the long (in the US) weekend.
Comment 9 Terence Ripperda 2004-05-28 15:47:35 UTC 
Carlos, can you include the output of "lspci -x -s 1:0"? thanks.
Comment 10 Andrew Bevitt 2004-05-28 18:02:52 UTC 
Mine works as this

Comment 11 Terence Ripperda 2004-06-01 08:07:38 UTC 
oh shoot, I actually meant "lspci -xxx -s 0:0". I really want to see the host-bridge's (via chip's) pci config space. I also need the "-xxx" to get more of config space, you'll need to be root to do that. thanks!
Comment 12 Carlos Eduardo Monti 2004-06-02 10:53:15 UTC 
The problem is solved. :)

I just installed a 520W power supply (old one was 300W), apparently... the recent motherboard+cpu+mem upgrade left my system slightly underpowered, enough to run but not stable.

In case you still want the lspci output, here it is:
