2.6.2-rc3: irq#19 - nobody cared - with an au88xx

[Daniel Jacobowitz]

I've started getting this, every 24 hours or so:

irq 19: nobody cared!
Call Trace:
 [<c010d38a>] __report_bad_irq+0x2a/0x90

handlers:
[<f886b290>] (au_isr+0x0/0xb0 [au8830])
Disabling IRQ #19

and then sound doesn't work for a while.

There's a good chance this is my fault.  IRQ 19 is:

 19:   18500001          0   IO-APIC-level  au88xx

and the au88xx driver is an out-of-tree driver that was developed on
2.4/early-2.5, and I ported it to 2.6 myself.  It worked flawlessly on
2.6.0-test7; has something changed in how interrupt handlers are required to
behave?

[Just ask if you actually want the source to this driver... I don't know
enough about the card to actually submit it to Linus's tree and the driver's
original authors aparently didn't care to.]
