>Description:
My stripped down kernel based on WSFBSBC does not boot and crashes
upon clearing the screen.

It clears only 1/4 of the screen on my Powerbook 160 (640x400x4bpp)
display.

I added some print statements to GENERIC with the grf device and if reports a video length of 0x8000 bytes which makes no sense as at best I
think it would be 640 x 400 / 2 bytes.

Serial console output to follow in a subsequent email.
>How-To-Repeat:
Try to boot the wsfb enabled kernels on a powerbook 160.

>Fix:
Not known.
