Still scratching my head :| Tony, this is the patch (modulo cosmetic stuff) that I sent to Giuseppe. I believe it's correct (I cross checked with X.org driver): diff --git a/drivers/video/nvidia/nv_i2c.c b/drivers/video/nvidia/nv_i2c.c index b858897..7e64341 100644 --- a/drivers/video/nvidia/nv_i2c.c +++ b/drivers/video/nvidia/nv_i2c.c @@ -70,8 +70,6 @@ static int nvidia_gpio_getscl(void *data) if (VGA_RD08(par->PCIO, 0x3d5) & 0x04) val = 1; - val = VGA_RD08(par->PCIO, 0x3d5); - return val; } Luca -- Non sempre quello che viene dopo e` progresso.
