Unfortuantely, gdb won't recognize my kernel dump:

finrod@niobe ~/crash$ gdb -k kernel.sym vmcore.0

kgdb could not open the exec-file, please check the name you used !
(kgdb) quit
finrod@niobe ~/crash$ file kernel.sym
kernel.sym: unknown pure executable not stripped

kernel.sym is the unstripped kernel.

(checking...)
root@niobe ~# camcontrol modepage -u 1 -m 1 -d
AWRE (Auto Write Reallocation Enbld):  1
