[Intel-gfx] Bug in kernel 2.6.32-11 (with intel drivers 2.11.0)

[Ant? Santos]

Hi,

I've been trying to setup a machine with a kernel-2.6.32-11 and Intel  
drivers 2.11.0.
However, each time I boot it with the TV set (or monitor) off, I get this:

Of course, after this, X won't start. If I start with the TV or  
monitor on, everything runs perfect. If I set acpi=off in the kernel,  
this error doesn't appear, X starts ok, but I will not get any signal  
on the TV if I power on it after the machine has started.
Any idea on how to fix this?

Thanks,

António Santos
