I launched Doom III and waited for it to freeze, then I ssh'ed into the
system and ran top.
The top most process was X (with some 99.9% CPU activity). Sometimes
doom.x86 (the Doom III process, of course) would rise to the top for a
few moments, but then go down again. The relevant lines from top:
When X was on top:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
11515 root 25 0 305m 32m 8824 R 99.8 2.2 0:45.56 X
1 root 16 0 2548 536 452 S 0.0 0.0 0:01.15 init
2 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0
When doom.x86 was on top:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
13237 keithvas 23 0 802m 715m 8320 R 97.3 47.7 2:04.93 doom.x86
11515 root 25 0 305m 32m 8824 R 2.4 2.2 0:36.50 X
13235 keithvas 16 0 10424 1276 928 R 0.2 0.1 0:00.38 top
My load average just kept rising, and rising. At a point it was 20.86,
8.14, 3.16 (whatever that means).
Before the game freezes, the top most process is doom.x86 (with around
85% CPU usage) and X comes in at third or fourth place.
Whilst the game is frozen, I occasionally here sound from my speakers.
Other times I hear nothing. When I'm hearing sounds, I'm able to type in
commands via SSH. When I'm not hearing sounds, nothing appears and the
system grinds to a halt. This suggests that (perhaps) the system tries
to recover but then is frozen again.
When I run strace on X, I keep getting the following:
rt_sigreturn(0xe) = 36984
--- SIGALRM (Alarm clock) @ 0 (0) ---
rt_sigreturn(0xe) = 36984
Doom III spawns several processes, here's what they say:
[ Process PID=13250 runs in 32 bit mode. ]
select(19, [18], NULL, NULL, NULL
[ Process PID=13251 runs in 32 bit mode. ]
getppid() = 13250
poll([{fd=15, events=POLLIN}], 1, 2000) = 0
[ Process PID=13253 runs in 32 bit mode. ]
gettimeofday({2811813141633945, 586448462527099936}, NULL) = 0
nanosleep({38654705664000000, 586448610090393576}, NULL) = 0
gettimeofday({2868712868371353, 586448630030824480}, NULL) = 0
I tried to reboot the PC. I did kill -9 (the X pid) and kill -9 (the
doom III pid), but when I looked at the machine's monitor it just turned
off (i.e. no output from the video card). I then tried to reboot via
SSH. The system looked like it tried to reboot, but then a garbled
screen appeared and nothing more happened.
The second time I tried this, kill -9 (the X pid) stopped sound coming
from my speakers, but the image just froze (i.e. frozen, not turned
off). I then killed doom, but the machine remained frozen. After this,
the machine completely froze (i.e. no commands, even from SSH).

Keith,
just a point on something you wrote in an earlier email. If you can
ssh in, then the system has not crashed as such. It would seem that your
video subsystem is stuck. Given that you can get in via ssh, is there
anything that is hogging the CPU that you can see via top. If so, get an
strace on it as this will help in debugging.
Another thing. Are you running in SMP mode?

When I bought the card, I was using kernel 2.6.12, I re-compiled that,
and it still didn't work. I also compiled 2.6.13 - still didn't work.
glxgears works. Also, some games like GTA: Vice City work with no
problems. Also, If I set the quality of graphics in Doom III to medium,
the game works.
It seems like only very intensive use makes the box die. It could be
something to do with the bug Andrew mentioned earlier (the bug is only a
problem with very intensive use). It can't be a hardware problem,
Windows worked.

I will not pretend to be an expert on this, but have you tried recompiling the

Also. do simpler 3D apps work? Such as glxgears? Try running glxgears in a
terminal...

The messages I get from dmesg after start-up show no errors - just that
AGPART is being loaded, finds a graphics card and everything seems normal.
I had already checked out the thread you pointed me to. The thread
provides a patch to fix the problem, but I'm supposed to already have
that patch - Gentoo have included it in their ebuild (of which I have
the latest, 7676).
I tried to figure out what they're talking about when they mention
global_flush_tlb(), and found this interesting post:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112928307319954&w=2
It seems, as is also said in the nvidia post, that this is being worked
on in kernel 2.6.14. Unfortunately, the thread I found mentions delays -
not total freezes - being caused by this "bug". The patch is against
2.6.14-rc4. I don't totally understand kernel terminology - but if the
patch is against rc4, does that mean it will be included in rc5?
Whichever it's included in, the latest (testing) kernel available on
Portage is 2.6.14-r2.
Seems like this will be a waiting game, unless anyone else has suggestions.

Do you get any messages after agpart module kicks in during startup? Did
you try some other forums besides gentoo? For example, I found this:

Hey Guys,
I've recently upgraded to an XFX GeForce 6800 GT from my previous card,
a GeForce FX 5200. Since having done so, I'm having problems playing
games.
When starting Doom3 in "Ultra high" or "high" quality mode, the game
locks up either seconds, or minutes, after the game begins. The whole
system freezes, neither CTRL+ALT+BACKSPACE nor anything else works.
Starting doom in "medium" quality mode seems to stop the problem from
happening, although I haven't played the game for longer then 30mins.
When starting Half Life 2, the game freezes a few seconds after the menu
is displayed. With Counterstrike: Source, the game loads a map, then
sends me back to the desktop.
Here's some information you may need:
Gentoo running amd64 on AMD Athlon 64 3000+ (Socket 939)
XFX GeForce 6800 GT (AGP)
1.5GB DDR RAM
cat /proc/driver/nvidia/agp/status:
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Disabled
SBA: Enabled
Kernel: 2.6.13-gentoo-r3
nvidia-kernel: 1.0.7676
nvidia-glx: 1.0.7676-r2
I've also used nvidia-settings to check the card temperature. 15mins
after boot, nvidia-settings reports:
Core Temperature: 44C
Ambient Temperature: 36C
I've searched through the Gentoo forums for similar problems, and this
has been reported one or two times, none of these people found a
solution (or posted about it). I looked on my motherboard for capacitor
decay (as described in another post) and haven't found any. I also don't
have X Composite extensions enabled.
Whenever the PC crashes, I can see the following in /var/log/messages (I
have to SSH to do this, the machine is too frozen to launch a terminal
locally)
Nov 3 22:05:06 silver NVRM: Xid: 25, L0 -> L0
Nov 3 22:05:06 silver NVRM: Xid: 6, PE0000 1f08 00000000 00000000

Nov 3 22:05:17 silver NVRM: Xid: 8, Channel 00000020
etc...
I've installed Windows on this machine and a few games just to test -
everything worked fine, so it can't be a hardware problem.
Any help would be greatly appreciated.
