It sounds like you've one a binary search to track this down and it's 
definitely that commit that did it?  I.e., if you specifically back out 
the associated changes to kern_malloc.c and malloc.h locally with a curret 
kernel, all is well?

Have you tried running with kern_malloc.c:1.141 (Jun 10) from Joseph 
Koshy, which corrects a bug in the deregistering of malloc types?

It looks like you're running with a serial console, but if not, could you 
do so and make sure there are no last second printfs that get eaten by the 
reboot clearing the video console?

Thanks,
