Hello,

I just tried recording audio on Freescale's MX28EVK that uses ASoC sgtl5000 (kernel v3.8) with:

    arecord -M -f cd sound.wav --duration 10

and got a scheduler message:

[ 789.041847] [sched_delayed] sched: RT throttling activated

I have just tested arecord on 3.8,4 and I haven't seen the 'soft lockup' bug.

However, I see that mxs saif gets busy after the record and any attempt to do an 'aplay' after the first arecord fails.

With the attached patch applied I am able to do arecord/aplay sequence several times.

I don't have a cable handy here to actually test if the sound is recorded properly or not.

Could you please test it against 3.8.4?

I managed to test arecord and it works with the following as follows:

1. Run alsamixer and select LINE_IN in the Capture element

2. Record with the following command line:

arecord -D hw:0,1 -d 10 -f S16_LE -r 44100 -c test.wav

3. Then listen test.wav on your PC or in your board itself.

The sequence above works fine.

Anyway, I will submit the patch I sent earlier as it prevents the system to get unresponsive.
