I got a dump and according to the instruction pointer and kldstat, it must be inside the umass, but I think something confuse gdb a little because that doesn't show up in the backtrace or maybe it is just me not knowing how to convince gdb to tell me: ########### angel:/var/crash # gdb -k /sys/i386/compile/ANGEL/kernel.debug vmcore.1 GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
