Hi!

I have an AMD Athlon 1.4GHz with 128M RAM and a Turtle Beach Montego
II sound card (I'm not sure what the mainboard is). The only other
peripheral driver I'm running is the tulip.o to drive my Netgear
ethernet card, but I doubt that that's causing a problem...

Well, I did this, and it seemed to work OK. I tried enabling it again
and having the interrupt do a printk() (in order to see if the pointer
being cast was good) before returning immediately, but it seemed to
lock me out of the keyboard (it could have crashed the kernel hard,
but I would never know) this time.

The code I had inserted into the interrupt handler went like so:

if (vortex == NULL)
{
  printk("vortex_t * vortex is NULL!");
  return;
}
else
{
  if (vortex->mmio == NULL)
    printk("vortex->mmio is NULL!");

  return;
}

It didn't print anything, so I'm assuming the pointers it got on the
first pass were good. I'll have to a bit more digging to see what's
going on...
