There seem to be several ways for suspend to fail. The "Restarting
tasks" problem comes from sound/soc/s3c24xx/s3c24xx-i2s.c
(s3c24xx_snd_lrsync), which loops forever.

We ever see the L/R index change, and "jiffies" never get incremented,
thus we never time out.

This looks as if quite a few things are happening in the wrong order
or not at all. I'll poke around this some more later.
