mysql on alpha?

[Idar Tollefsen]

What this means is that MySQL is trying to access memory not aligned on 
4-byte boundaries. The system fixes this for you, but prints these warnings.

There are some sysctl variables you can play with here. You can either 
just turn off the messages by setting machdep.unaligned_print to 0 or 
you can debug the problem by compiling MySQL for yourself with debug 
information and force it to crash. You force it to crash by setting 
machdep.unaligned_sigbus to 1.

Printing these messages can also be turned off by setting 
unaligned_print="NO" in rc.conf.

This is for 4.x btw. Not sure if these things works the same on 5.x.
