Funny thing is, that when using ZFS file-system for installation, it finishes properly, but when I switch to UFS + Softupdates this panic occurs like clockwork. That may not be related, but it is a weird quirk none the less. Screenshot of panic: http://www.pcbsd.org/~kris/kerndump/panic1.png Core file: http://www.pcbsd.org/~kris/kerndump/vmcore.0.gz Let me know if you need additional info. (As an aside, seeing similar panics on 8.0 / 8.1, when our installer is doing pkg_delete / pkg_add stuff in the disk chroot environment) >How-To-Repeat: Just starting an install of PC-BSD / FreeBSD 9.0 snapshots, works fine until it gets into heavy duty pkg_add stuff, then this panic occurs. >Fix: Using ZFS works, but it may be an unrelated quirk. >Release-Note: >Audit-Trail: >Unformatted:
