Hello, maybe this is "a bad thing to do", I'm trying to to change the active partition on the device (ada1) which is booted from in single user mode. I changed kern.geom.debugflags to 16. Calling fdisk with -a or -u flags, panics immediately: panic: spoiling cp->ace = 1 Maybe it is related to kern/112707, but I don't know. The panic only occuers, if there is no swap partition enabled. Doing a swapon /dev/ada1s4b for instance before the fdisk call does not yield to the panic. I could not find any mention of this issue in the fdisk(8) or swapon(8), geom(4) has a section about spoiling, but I couldn't figure out how this is related to swaping or fdisk. I can't remember having to use swapon before using fdisk in the past (but I'm not sure...) If this is a requirement, I think it should be documented somewhere in fdisk(8). Note that the panic does also not occur if kern.geom.debugflags is 0. uname -a FreeBSD antec 9.0-BETA2 FreeBSD 9.0-BETA2 #0: Sat Sep 17 12:51:24 CEST 2011 root_at_antec:/usr/obj/usr/src/sys/GENERIC amd64 Below is a backtrace and the kernel config, I can reproduce the panic every time in this setup, how should I proceed to get more information form the dump?

Enter 'tr' to connect to the remote target with /dev/cuad0, 'tr /dev/cuad1' to connect to a different port or 'trf portno' to connect to the remote target with the firewire interface. portno defaults to 5556. Type 'getsyms' after connection to load kld symbols. If you're debugging a local system, you can use 'kldsyms' instead to load the kld symbols. That's a less obnoxious interface.
