What hardware are you seeing the problem on? I'm wondering if this might be a CPU capability dependent bug because I don't get the error on a new Ubuntu Server 12.04.1 32bit installation in a VM on a VMWare ESXi 4.1 host running on a PowerEdge R710 with dual Xeon L5520 CPUs. I do get the problem with an Identical version of Ubuntu freshly installed and updated on an older Compaq DL380 server that has dual PIII 1.4 GHz CPUs.
