Greetings,
A server of mine kernel panicked and in the serial console it prints non stop these messages which
are repeated again and again..

This machine will be rebooted on Monday, so from the time being I can only watch these messages repeated
again and again. This server is mainly used for virtualization (virtualbox) and has ZFS, on a Sil 3112 and
Intel 6300ESB SATA150 Controllers. I think that either the Sil controller or memory exhaustion due to ZFS and
virtualbox has occured.
How can I figure out what has really happened? Can I issue any command from the serial console?
Thank you
