>Description:
I have a system with all standart daemons running with no load. I have no problems on local console, but when I login via ssh I face with a pause of input/output which resume after 10-60 sec. Such events can repeat every 1-5 minutes. They are quite random: for example connection can hang while I typing something in a text editor on in the shell.

The system installed from 7.1-RELEASE-i386-disc1.iso
This bug manifested also with GENERIC kernel
>How-To-Repeat:
Connect via ssh and wait for a few minutes.
