Transfer from internet stops when the cpu/hdd's are active.

[Spacecake]

I used to use RedHat 6.2, and the default kernel that came with that.
I had gotten used to the fact that while downloading something, if i didn't touch anything it was fine... but as soon as i loaded an app up or caused any kind of disk/cpu activity the transfer would stop until it had finished... whereupon it would carry on.
I know this from watching the gkrellm ppp graph.

Anyway, i recently got Slackware 8.0, and using the precompiled kernel 2.4.5 it came with... it no longer had this problem. I was extremely pleased - now i could load apps, compile programs and allsorts without affecting the transfer rate at *all*

A few days ago i had to compile my own kernel (so i could install NVdrivers), but i have noticed that now... the old problem with downloading stuff i had in redhat is back.
So... i am assuming this is an option in the kernel configuration that is different between my custom 2.4.7 and the Slack8 2.4.5. I looked through all the options and can't find *anything* that mentions this.

Has anyone else run into this problem? If so, do you know how to correct it?

It may have to do with irq priority, I'm not sure where that stuff is in the kernel source though. Maybe I'll look some day :)

You might find this interesting: http://www.best.com/~cae/irqtune/

also make sure you have dma on your hard drives enabled if your system can run stable with it.

Edit: One more suggestion, this might sound odd but try reverting to the "nv" driver and see if the problem goes away at all.
