I have text 80x30 mode set at rc stage, and _after_ that may have many kernel messages on console, all without causing reboot. How it is different from shutdown stage? Syscons mode is unchanged since rc stage. > - sysctl debug.kdb.break_to_debugger. This is documented in ddb(4), but > only as equivalent to the unbroken BREAK_TO_DEBUGGER. Thanx. Setting debug.kdb.break_to_debugger=1 makes both Ctrl-Alt-ESC and Ctrl-PrtScr works in sc only mode and "c" exit don't cause all chars beeps like in vt. I.e. it works. But I don't understand why debugging via serial involved in sc case while not involved in vt case and fear that some serial noise may provoke break. Is there a chance to untie serial and sc console debuggers? _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
