Are you able to break into the debugger at this point? Try setting debug.kdb.break_to_debugger=1 and debug.kdb.alt_break_to_debugger=1 at the loader prompt, and hit the break key, or the key sequence <CR> ~ ctrl-b once the hang occurs. At the debugger prompt, try "bt" and "show allpcpu" to start. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
