I have mailed about this 2 weeks ago but received no response, so I'm trying again:) The changes to syscons.c in the last month or so panic my machines that do not have a screen but have syscons in the kernel (they only have a serial terminal). It happens somewhere in the attach routine during a bcopy. This led me to look through the the syscons.c file. One thing that bothers me is that the probe can never fail. It assumes that there is a screen. In the attach routine it will check if it is a colour screen otherwise it reverts to monochrome. Shouldn't the probe determine if there is a screen and fail if there isn't? With the other changes in the kernel and the boot blocks one would assume that you can have a kernel with syscons compiled in and the syscons probe will just fail and go on with your console on the serial port, which does happen by the way, I do see the panic message on the serial terminal. Anyone care to comment? -- John Hay -- jhay@mikom.csir.co.za
