I've never had to use kgdb before. This is a dell 1750 (poweredge). I'm 99% sure it's not hardware related since putting the drive into other stable machines (other dell 1750's) makes them crash as well using: bacula-fd shutdown -r now Note: I also get the same crash when trying to install python from the ports (crash at: configure: checking for pthreads..) cd /usr/ports/lang/python24; make install
