But is it > really necessary to disable VGA beyond that? Yes, it is. Otherwise it oopses as soon as something is printed on /dev/tty. Quite early at boot with "console=3Dtty1", otherwise as soon as /sbin/getty starts on /dev/tty1. Oh, and the reason is it thinks it has an EGA card with 0 lines and 0 columns because we never ran the real-mode boot code and thus SCREEN_INFO isn't initialized. The 0x0 screen probably leads to the zero-sized buffer you are catching in that patch. cheers, Gerd -- = Gerd Hoffmann
