Trace on HD6320 after resume on v3.7-rc6

[Julian Wollrath]

Hello,

while having problems with the resume of the snd-hda-intel driver, I
found the following in my dmesg output:
[  245.003310] irq 16: nobody cared (try booting with the "irqpoll" option)

I was not able to reproduce it but maybe the trace is helpful
nevertheless. I got it during the resume after a suspend to ram.

If you have further questions, please feel free to ask.


With best regards,
