[Bug 63165] <3>BUG: soft lockup detected on CPU#1!

Public bug reported:

I've just installed Server 6.06 on a dual-CPU Asus A7M266-D.

I also installed the LAMP packages, webmin and sshd.

I left the server ticking over for a soak test with no customisations or
web applications installed.

After about 18 hours it crashed with the following report in kern.log. I'm not sure from the report where to being looking to debug this.
Since rebooting uptime is 38 1/2 hours, again just ticking over.
