This server runs an e-mail server, a windows 2003 server, a windows xp machine
and 2, a firwall (linux based) and a pbx (linux based).

The problem is that sometimes (and very randomly) the server freezes (usually
during the weekend) and the only "strange" think I can find is a bug in the
libata-core.c:

Here is a part of the dmesg:
