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. -- Cheers Denis Barov
