[alsa-devel] Hung task with trace after resume on kernel v3.7-rc6

[Julian Wollrath]

Hello,

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]

After resuming after an suspend (either to ram or to disk) I found this
output in my dmesg:
