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
