Default NForce driver - is it worth it?

I have an Asus A7N8X-E Deluxe board, and everything works fine, except from the S-ATA driver which makes the whole system freeze while it's under heavy load, so I was wondering if the nForce driver could fix this.
What does the nForce driver has that a vanilla kernel doesn't?

What do you mean by "nForce driver" versus vanilla kernel?

Are you using libata or the old kernel SATA driver? In the kernel config it's under Device Drivers->ATA/ATAPI/MFM/RLL support->Enhanced IDE...->Support for SATA (deprecated: conflicts with libata SATA driver)

I have been using the newer libata on several nForce machines, one of which is my development VMware machine that is totally hammered all day long without issues (although that is a nForce3 Pro machine).

nForce driver as in this: http://www.nvidia.com/object/linux_nforce_1.0-0301
I just discovered the release notes, so that's cleared up.

I'm using libata. The problem is, during heavy disk usage, the whole system freezes (the sound stops, everything just freezes, even numlock isn't working).

Sounds like some sort of kernel panic. I have found the easiest way to spot those is to either get it to crash while you are at a console window (in which case the dump will pop up on screen) or connect a serial terminal which will also show the dump. You could start the heavy process and then CTRL-ALT-F1 or whatever to get to a console and then wait for it to crash.

If you can get that dump/trace then you will probably be able to see what is causing the problem.

Do the SysRq magic keys still work? (has to be turned on in your kernel)

It doesn't crash like that, it just freezes temporarily while working

Oh, heh, yeah that's not as bad then. How long does it freeze for? It's somewhat normal to freeze for a second or two when writing lots of data to the disk. If it's stopping for a long time (like 30 seconds or something) then you should check your /var/log/kern.log for error messages as it's probably getting timeout errors or something (I get these when using firewire devices heavily).

It's never stopping for more than about 10 seconds, but it's really annoying. I always think something went seriously wrong.

I just put an ASUS A8N-SLI Premium(nForce4) on my system and my system would lock and give me a kernel error when using the nvidia SATA controller. After some research I found that putting noapic in the kernel parm it fixes it.

I have also experienced the same thing when running some of the power management stuff where it tries to control the CPU frequency. When the machine would get under load it would start doing its thing and the machine would freeze occasionally.

I think you may find that that is the NVIDIA GFX driver that is causing that. I'm assuming here for a moment that you have a GeForce running under X/Xorg with the NVIDIA graphics drivers?

That's correct. I have a GeForce 4 ti 4200 running under X, but I can't see how that's causing the freezes.
