I realise that there is another problem with these machines relating to the SMAP as reported in 111952, but this appears to be different. I see the SMAP probelem if I boot in amd64 (with or without ACPI enabled) but under i386 it simply panics before even getting to that stage. I am using the latest BIOS from HP, and a version of -STABLE from two days ago (November 6th). >How-To-Repeat: Attempt to boot a 6.3 kernel on one of these machines with ACPI enabled. >Fix: Disabling ACPI enables the machine to boot - but it then requires the amount of physical memory to be set by hand in loader.conf and cannot see the 2nd processor. >Release-Note: >Audit-Trail: >Unformatted:
