I recently have been doing heavy investigation into using Linux for NAS=20
with an Intel E1000 and
Slackware 8.

I found this problem also, however it disappears if you use PowerTweak=20
Daemon and get the latest
driver for the Intel Card.

But PowerTweak cured alot of my issues...

Hope this helps

We've also got problems with nfs-hangs when transfering large files (ie.
files around 300-400M, sometime we have to go a bit higher tho, like
2GB-3GB files, but it's always possible to trigger this. However, we
don't need to be jumping through hoops to "fix it", after a min or so,
it's ok again. It seems to me like there's a VM problem or something.

We've got 2GB mem on the machines which are suffering from theese=20
problems.
