Are the kernel configs really *completely* i= dentical aside from VT vs. syscons? VT uses the same code on PPC to use the f= ramebuffer as syscons and doesn't touch any of this other stuff. 10.1 also d= oesn't have vt in GENERIC -- only 11 has that. Are you sure you didn't insta= ll an 11 image instead? > -Nathan Yes, the only diff was commenting sc out and putting vt in. I even named the modified version VTGENERIC to remember that this configuration shall never carry any other changes. --jau
