X-Mailer: ELM [version 2.4ME+ PL31 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Busy machine runs days no problem. Recently when trying to backup the files systems the machine hangs/locks up. I had been trying to use compressed tar to the tape. It manages to do various amounts of data (at least several Gigs) and sometimes even completes without a hitch. However when it hangs it really hangs. Requires power cycling. If I just reset the box then it requires going into the BIOS and resetting the PCI/PnP settings. Here is the errors the preceeded that last meltdown followed by the dmesg output for this box.
