>Description:
It correctly find pcm0 on irq 5, dma 0,1, ports 0x220,0x530,0x388,0x330
but then i play smth thru this device, even cat /dev/urandom > /dev/audio
it hangs after 3-20 seconds of play, even without panic
This problem exist in 5.0-CURRENT too. I think this is a bug in pnp,
because Yamaha works with 2 irqs 5 - sb emul, (9|10) for mss emul/native
it works under 3-STABLE if i use pnp 1 0 irq0 9 irq1 5 etc... but i could be wrong...
>How-To-Repeat:
device pcm in kernel config
Yamaha OPL3 Sa2
pcm0: <Yamaha OPL-SAx> at port 0x220-0x22f,0x530-0x537,0x388-0x38f,0x330-0x331,0x370-0x371
 irq 5 drq 0,1 on isa0
>Fix:
May be pnp_quirks help? Or this bug is in newbus?
Please mail me if you could explain how to use pnp_quirks to set irq 9
for this card.
