I have never seen this panic again, and with the recent ACPI commit by John Baldwin ( http://lists.freebsd.org/pipermail/cvs-src/2004-January/017369.html) I have not had any problems with ACPI. I am sorry for not offering much help, but I thought I'd let you know you're not the only one with Pentium II and has seen this type of panic :/ -- Morten Rodal
