Hi there,
As of 2.4.5-ac4 (maybe -ac3 too), my sound card (a cs46xx) has stopped
working. Looks like there's something wrong with the interrupt handling code
because the device remains busy, I get weird lockups after having run and
^C-ed sndconfig. Also, when I look at /proc/interrupts after sndconfig, the
IRQ for the sound card seems stuck at 0.
I've seen changes in the driver code, but they don't seem to have much to do
with the interrupt handling.
Any ideas?

The locking fixes broke it. I'll try and take a look at it this weekend. Its
probably just a missing init_MUTEX() somewhere
