I rebuilt my 6.4-STABLE amd64 kernel with the following options to try an track down an issue with a patch. options KDB options DDB options GDB options BREAK_TO_DEBUGGER options INVARIANTS options INVARIANT_SUPPORT options WITNESS options DEBUG_VFS_LOCK I then built and installed the resulting kernel.debug no issues there I then set in /boot/loader.conf dumpdev="/dev/da0s1b" When I reboot and crash the box on the new kernel at the db> prompt I cant "call doadump" to work or get an automated one from "continue" both complain about no dumpdev defined . Does anyone have a solution for this ? -- Mark Saad mark.saad@ymail.com
