I've followed the procedure at http://www.vinumvm.org/vinum/how-to-debug.html, and now I have some more symbols (look at #28, #29 and #30). Unfortunately, the output of 'f 1' does not have de "vinum debug" line in it, I don't know if it should (I was going from singleuser to multiuser when the panic took place). My debug environment is (long lines): (20:38:06 </var/crash>) 0 $ ls -al total 284536 drwx------ 2 joan wheel 512 Oct 28 20:31 . drwxrwxr-x 9 root wheel 512 Oct 28 11:57 .. -rw------- 1 joan wheel 60 Oct 28 20:35 .asf lrwx------ 1 joan wheel 14 Oct 28 20:29 .gdbinit -> .gdbinit.crash -rw------- 1 joan wheel 77 Oct 28 20:29 .gdbinit.crash -rw------- 1 joan wheel 15196 Oct 28 20:29 .gdbinit.kernel -rw------- 1 joan wheel 80 Oct 28 20:29 .gdbinit.serial -rw------- 1 joan wheel 8729 Oct 28 20:29 .gdbinit.vinum -rw------- 1 joan wheel 557 Oct 28 20:29 .gdbinit.vinum.paths -rw-r--r-- 1 joan wheel 2 Oct 28 18:49 bounds -rw-r--r-- 1 joan wheel 2925320 Oct 28 18:22 kernel.0 -rw-r--r-- 1 root wheel 2925320 Oct 28 18:49 kernel.1 -rwx------ 1 joan wheel 10857762 Oct 28 20:30 kernel.debug -rw-r--r-- 1 joan wheel 5 Oct 28 12:50 minfree -rw------- 1 joan wheel 536870912 Oct 28 18:22 vmcore.0 -rw-r--r-- 1 root wheel 536870912 Oct 28 18:49 vmcore.1 (20:41:20 </var/crash>) 0 $ cat .asf add-symbol-file /modules/vinum.ko $file->address+0x00006c74 (20:41:25 </var/crash>) 0 $ file /modules/vinum.ko /modules/vinum.ko: ELF 32-bit LSB shared object, Intel 80386, version 1 (FreeBSD), not stripped (20:41:27 </var/crash>) 0 $ objdump --section-headers /modules/vinum.ko | grep text 3 .rel.text 00003ed0 000021cc 000021cc 000021cc 2**2 7 .text 0000be44 00006c74 00006c74 00006c74 2**2 qvb -- pica
