MD_ROOT and MFS_IMAGE options in 7.2 causes kernel trap

[Denis Barov]

Hello, list.

I try to migrate one of my MFS-based system from 7.1 to 7.2 and get kernel
trap 12 just after DDB initialisation
(screenshot: http://dindin.ru/download/kernel_trap.png)

FreeBSD svn revision: r199991, architecture: amd64

there was a lot of changes in sys/amd64/amd64/pmap.c and can't really
understant which can cause this.

I'll appreciate any help.
