Tyan Tiger MPX + Quadro4 750 Freezes
Hi all,

We are using RH 7.3 with kernel 2.4.18-3 smp

this is our system configuration

Tyan Tiger MPX motherboard
Dual 2400MP Cpu's
2GB DDR Ram-Kingston PC2100 512MB ECC Reg Modules
PNY Quadro4 750XGL OpenGL Card with 128mb ( AGP)
Adaptec Raid Card 2400A connected to 120GB x 4 Nos in Raid5 Mode
80GB (7200rpm ) system Drive
Intel Gigabit Server Adapter
Pioneer DVD Drive
1.44 FDD
Two 19inch monitors
Nvidia Linux Drivers Version: 1.0-4363
Operating System: Linux IA32
Release Date: April 24, 2003

We are facing random crashes on this system many times in a day, the crashes
normally either makes both our monitors blank out and the keyboard will freeze and we
have to either do a Reset or Power Off and then Power on the system

The crashes do not occur at any particular place, it crashes sometimes while working in our Compositing
application - SHAKE or while coping files

I have gone through the Linux Discussion forum and looks like this problem was faced by
many people using AMD based systems.
( we have two Xeon based systems with same configuration and they run SMOOTHLY all the

From what I have understood is that people having been talking about the following points
to solve these SMP freezes

1. Use the AGPGART patch for AMD systems .

Q: Should I use this ? If yes does the Nvidia 4363 drivers automatically do it or do I have to
compile the kernel in any way?

2. Mem=NoPentium setting

Should this setting be done on my AMD system? if yes how should I do it?

3. People have advised using the 2.4.18-10 kernel instead of the 2.4.18-3smp kernel I'm using

Pls advise which one should I use - or do u suggest using a new kernel version altogether?

4. noapic option at bootup?

Should I use this? if yes should it be done in bios or in the Linux Kernel?

I need to make my system stable as we are suffering in our Production schedules,
pls advise on the above points.

All yr inputs will be highly appreciated.

Can anyone please help here?

what power supply are you using with the above unit? Is it on AMD/Tyan's list of certified units?

You might also want to try a more recent 2.4.20 kernel.

one thing to try would be to remove the SCSI card and unplug the power from all of the SCSI drives and see if the problem persists.

my computer has very similar configuration: Tyan 2466, dual athlon 1800mp, adaptec 39160, geforce 5800... I have 6 different linux distributions installed. my x crashed several times, but every time i was able to kill it at least with <alt>-<sys rq>-<k> (if your kernel supports magic sequences). no single freeze neither with geforce nor with my old matrox for more than year.

I have almost the same configuration than you, only I got a Ti4400 instead of a Quadro and I got the Tiger MP instead of the MPX. First I would check with 3123 drivers, it seems they are far more stable than 4xxx, just take a look at my "Stress testing 4xxx" post.
