I have an Thinkpad X121e with the following soundcard: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] [1002:1314]
Of course I did not mean the hdmi device but this one, sorry: 00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) [1002:4383] (rev 40)
So, for this particular issue (at least the recursive suspend call), I think the easiest way is a patch like below. This is no ideal solution but would be good enough as a bandaid at this late stage for 3.7. Julian, could you check whether this works?
Sadly the patch does not work, I still get the spurious responses and a trace, which looked minimaly different this time: [ 240.434881] INFO: task kworker/u:14:3617 blocked for more than 120 seconds.

By the way, it seems like I get the traces every 120 seconds and not only once, forgot to mention that earlier.
With best regards, Julian
