I also have a K7S5A MB, and see the same thing. I don't think it's
temperature related, but that there's a bug/quirk we aren't dealing with.
Whenever I see these problems, I have to reboot the machine. Nothing else
I've occasionally seen the problem when I first power up, so I don't think
Also, I can failry reliably cause the problem by shoving a LOT of data
over the link. Like when I was first installing, I'd try to tar my msdos
partition to an NFS-mounted file system. The tar would alway die on the
first large file it found. I had to end up getting a different ethernet
interface for the machine to do the install.
