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
This command works on v3.8 even without your patch. I can arecord/aplay several times
without problems.
With my original command 'arecord [-M] -f cd sound.wav --duration 10', the soft lockup
appears both in v3.8 and v3.8.4 with and without your patch. So it looks like the
patch does not help here.
