It panics at boot time right after the probes complete with the following message: panic: vm_page_alloc: offset not page aligned The panic is within a #DIAGNOSTIC ifdef block. The last good kernel I have was built from sources supped sometime during the morning on 7/13, and that kernel does contain the new vm changes. Here is a traceback from the dump. I don't have time right now to examine this any further. Reading symbol data from /usr/var/crash/kernel.12...done.
