I'm running 2.5.40 on a cutting edge via embedded C3 motherboard. When I turn off CONFIG_FB and CONFIG_VGA_CONSOLE I get this during bootup: Unable to handle kernel NULL pointer dereference at virtual address 00000004 printing eip: c01e5a1d *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0060:[] Not tainted EFLAGS: 00010246 eax: c6ee4a00 ebx: 00000000 ecx: 00000001 edx: 00000000 esi: 00000000 edi: 00000000 ebp: c0399dc0 esp: c116fe70 ds: 0068 es: 0068 ss: 0068 Process init (pid: 1, threadinfo=c116e000 task=c116c040) Stack: c6ee4a00 00000001 c6ee4a00 00000000 c01e5af8 00000000 00000001 00000000 c6427000 00000000 00000401 c116fec0 c01e924f 00000000 c6427000 00000001 c01d8b58 c6427000 c6ed9120 01024180 c6427000 c6bba2d0 00000006 c116ff70 Call Trace: [] [] [] [] [] [<] Code: ff 52 04 8b 83 c0 9d 39 c0 5a 59 66 83 78 22 00 75 17 ba 00 <0>Kernel panic: Attempted to kill init! This is inside drivers/char/vt.c in vc_allocate just after the visual_init call. Related configs are: CONFIG_VT=y CONFIG_VT_CONSOLE=y CONFIG_HW_CONSOLE=y CONFIG_SERIAL_8250_CONSOLE=y If I turn either CONFIG_FB or CONFIG_VGA_CONSOLE back on it boots fine. With CONFIG_FB I don't actually have any other FB related settings on and I never actually use the frame buffer device. Let me know if more information is needed.
