Indeed, this is how Linux will behave after the probe / console env thing is fixed. I assume your more than minimal necessary probe has the purpose to make shut that the machine does not only have gfx but also that the gfx found in the address space is not something else like the XZ for example? William Ellis: could you try to set the ARC environment variable ``console'' to d1 / d2 according to the port you're using and run the kernel you've tested once again? Ralf
