Not terribly likely as the reboot does occur. It looks more like one of the drivers is leaving hardware in a state that the BIOS cannot deal with it. My gut feel says kexec one linux kernel from another would be a quick way to check for the move obvious driver problems in this area. More simply might be to boot a minimal kernel with just your root filesystem drivers and then keep adding drivers until you have a kernel that fails. The SMP reboot path did change in 2.6.10 but only very slightly.
