Hello, While investigating a problem with one server i installed a serial console on it. The machine has a supermicro board with console redirection enabled on the same port, and everything seems ok, i.e. when the machine panics i get a debugger on the serial console, but when i try to manually escape to the debugger with BREAK (~#) i get this on the screen : The following connections are open: #0 client-session (t4 r0 i0/0 o0/0 fd 4/5 cfd -1) Manual enter to the debugger works only if i go physically to the keyboard and do a CTRL-ALT-ESC, then i get KDB: enter: manual escape to debugger on the serial console. i have this added to my kernel conf : options BREAK_TO_DEBUGGER options KDB options DDB and this in /boot/loadaer.conf : console=comconsole Maybe the fact that there is physically attached keyboard interferes with the serial console? Regards, Niki Denev
