I feel you pain, but since I only have a Tyan mp 2460 our hardware is a little
bit different. I am running testing with a 2.6 kernel, and am having no
problems. That being said I also use a journaling file system. I have used
ext3, and assume you are using ext2, what kernel parameters are you pasing to
the kernel? I use the noapic and acpi=off with good results, but some people
can not tell the difference. Is their a reason you have not tried a 2.6
kernel? I know you are using woody, but you might want to consider upgrading,
if you decide to go to sarge.
A while back I did have some weird problems with a 2.4.25 kernel, could never
figure it out either, I was using a Reiserfs and got some corruption, but to
be honest I believe its chipset related. Here is why, in this system I have
a CrystalFontz LCD which I use to monitor different systems specs. My
harddrive is on a single primary, and I have two other drives sharing
another IDE, durring heavy system use, say I use unrar, burning a CD or
something else, sometimes in my system logs and on screen I get, serial line
busy and it shuts down my Crystal Fontz LCD. Then if I try to restart it,
like normal it won't come up, I have to go to init1, even then it sometimes
does not comeup, until I reboot. So it would not surprise me if the chipset
is flakey, also do you use a usb mouse, or keyboard? I know for at least the
mp 2460 just having this has been know to lock the system up.
I would suggest trying a 2.6 kernel, if your using testing or sarge, and just
apt-get the k7 smp kernel image and see how it works with your DMA settings.
Also I know that some mp mpx motherboards do not like certain graphics cards,
I had a Nvidia 5600 ultra, and worked in mine, but Tyan does not support the
FX series on my board. http://forums.pcper.com/showthread.php?t=265196 since
then I switched back to a geforce2, that I rebuilt, put that ultra in a
single cpu system, which is used to play Doom3.
As far as knowing a silver bullet for fixing DMA in 2.4, I am at a loss other
than what I said above.
