[Dri-devel] Re: PIO&locking disabling

[F. <j_r...@ya...>]

I've overcome this, but sursprisingly there is no further segfault. I see 
all the debuging statements scrolling in my terminal without stoping.

This either means that the problem is at the locking mechanism or in the 
register programming in _tris.c.

I'm really suspicious about the locking because when I first disabled the 
MMIO (since the driver doesn't really do PIO) and forgot about disabling 
the locking the my computer also hanged. How can this be? Since when the 
locking is overriden the computer doesn't hang this means that the problem 
must when locking.

Any ideas?

Later on I'm going to see if I can get another laptop from a friend of 
mine to make further debugging.
