I just checked, and my 9.2 and 10.0 boxen have them by default; but they can be turned off.

Since you're using GENERIC, can you extract a fresh kernel from the distribution and see if that exhibits similar behaviour, just to narrow down a possible intermittent hardware issue? For example: I have an SSD in one of my machines that functions perfectly fine unless the machine is warm-rebooted, when it will disappear sometime between loader and mountroot. Only a power cycle can bring it back. Another thing you might try is to switch the root mount in fstab or loader.conf to using a glabel device, like /dev/ufs/<label> or /dev/ufsid/<hex-id>, and see if that works where the ad alias failed. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net <CyberLeo@CyberLeo.Net> Furry Peace! - http://www.fur.com/peace/
