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?

Thanks,

Fabio Estevam
