I have a new, fairly generic i386 box, with a fresh install of 7.0-RELEASE using pretty much the default options. I'm using a generic kernel with the addition of "options GEOM_BDE". I have had a couple of panics with it over a day or two; I can't pinpoint what is causing it, it has panicked when I'm not there and nothing seems to be going on. I recompiled the kernel shortly after install, so don't know if it will panic on the generic kernel alone. There is a vmcore in /var/crash, and I followed the instructions at http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneld ebug-gdb.html However, I'm not sure if kgdb is telling me I have a physical memory problem, or if it is telling me it's not working properly, (or more likely I'm not using it properly): odin2008# kgdb kernel.debug /var/crash/vmcore.1 [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
