It looks like isa/sio.c still won't allow you to set a port as both a low-level console and the gdb port. I could not get remote gdb to work correctly after the sio probe without designating the port for low-level console I/O. Now that I've done that, I can't debug at 115200 any more. 38400 seems to work for me, but that is with only minimal testing. Who broke remote debugging in sio? This is a critical tool we can't afford to have broken... 8-( -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
