We have some systems we are upgrading from FreeBSD 6.1 to FreeBSD 6.3. These are Dell PowerEdge servers. The one I'm working on now is a 1950. Under 6.1 it booted into SMP mode no problem. Under 6.3, with no changes made in the BIOS settings, it does not. Here is the start of the dmesg: Jun 17 11:03:26 master1 kernel: Copyright (c) 1992-2008 The FreeBSD Project.

We've double checked that we have both 'options SMP' and 'device apic' in the running kernel. I've done a lot of googling, and have come up with nothing that seems relevant to our situation. The most puzzling thing is that this worked fine under 6.1 on these same machines.... --David
