My thoughts on why it was possibly similar is that it happens [ 793.932076] kernel BUG at mm/slub.c:2834! where as 20702 is kernel BUG at mm/slub.c:2835! the rest didn't line up, and like I said I haven't specifically dug into it. As a note I did end up with a full panic in the last hour, but nothing got recorded (sadly). I'm working on getting the kernel compiled up with everything now so hopefully I'll start getting some additional data to share. - John 'Warthog9' Hawley
