https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=183024 --- Comment #4 from sigsys@gmail.com --- (In reply to Andriy Gapon from comment #3) Sure seems like you did! Thanks. I forgot to check if it had already been fixed after finding this PR. For reference, I just checked if making sure that debug.ddb.textdump.pending is set or that having "textdump set" in the DDB script is necessary, and it is not. "textdump dump" tries to do a textdump no matter what. I wish the manpage gave some pointer to "debug.debugger_on_panic" though (I had the KDB_UNATTENDED option when trying to set this up and ddb wasn't being invoked at all).
