So far we have reports from both camps:
Asus M2N8-VMX (AM2): 1 report of lockup
http://sourceforge.net/mailarchive/forum.php?thread_name=46780384.063603.26165%40m12-15.163.com&forum_name=atl1-devel
Asus P5K (LGA775): 2 reports of lockups
http://sourceforge.net/mailarchive/forum.php?thread_name=467E7E34.4010603%40gmail.com&forum_name=atl1-devel
