    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
