removing radeon_acknowledge_irqs hack..

[Dave A. <ai...@li...>]

In radeon_irq.c:radeon_wait_irq

There is a comment
/* This is a hack to work around mysterious freezes on certain
 * systems:
 */
        radeon_acknowledge_irqs(dev_priv);


On my 7500 system I've been seeing mysterious hangs after a week or so
running, and I've removed this "hack" from my system and my hangs seem to
have gone away, I've talked to Keith about it and he can't remember
exactly what it fixed but he remembered never producing it on his own
system, and it is a bad idea IMHO..

I'm mainly sending this mail as I can guarantee about 5 mins after I send
one of my machines wil hang :-)

Dave.
