One of the developers better comment on those messages.

It sounds like it. Did you build this filesystem with any special mkfs options?
What IDE controllers are you using? Did you use the 2.4.18 kernel that came 
on the installer disk or is this a selfcompiled version or even a CVS checkout?

Weird. I frequently have to copy large amounts of data over the network and 
it works fine so I suspect that something in your filesystem is not right 
and causing it to fail again as soon as you try to copy to it again.

Can you check/repair the filesystem and see if it appears again?
